An event flag is a process synchronization primitive in the OpenVMS operating system. It has two possible states, set or cleared. The following basic primitive operations are provided.

Wait for event flag ($WAITFR)--if the flag was clear, this would make the process wait until it was set. If the flag was already set, this would immediately return, leaving the flag set.

Event flags can be either local (per-process) or common (accessible by more than one process). Each process has its own set of 64 local flags, numbered 0-63. It is also possible to associate the process with up to 2 sets of common event flags. These come in sets of 32 each, and the process can assign them numbers 64-95 or us. They come into existence when the first process associates with them, and disappear when the last process removes its association. Every potentially time-consuming asynchronous system call (QIO among others) includes an argument specifying the number of an event flag to set on completion. Compare semaphore.

Portable flag poles allow your banner to receive maximum viewing for your event display or exhibition event. These exhibition flags, event flags and promotional flags are Lightweight and portable, highly mobile systems to promote your graphic display and fabric flags. There is no need for planning permission, as these flags are quick and simple to erect and ideally suited to outdoor and indoor events. Our Portable Flags are printed on lightweight flag material and can be printed single or double sided.

Event flags allow a consumer thread to wait for one of several different types of event to occur. Alternatively it is possible to wait for some combination of events. The implementation is relatively straightforward. Each event flag contains a 32-bit integer. Application code associates these bits with specific events, so for example bit 0 could indicate that an I/O operation has completed and data is available, while bit 1 could indicate that the user has pressed a start button. A producer thread or a DSR can cause one or more of the bits to be set, and a consumer thread currently waiting for these bits will be woken up. Unlike semaphores no attempt is made to keep track of event counts. It does not matter whether a given event occurs once or multiple times before being consumed, the corresponding bit in the event flag will change only once. However semaphores cannot easily be used to handle multiple event sources. Event flags can often be used as an alternative to condition variables, although they cannot be used for completely arbitrary conditions and they only support the equivalent of condition variable broadcasts, not signals. Before an event flag can be used it must be initialized by a call to

Data structure, which can be part of a larger structure. All 32 bits in the event flag will be set to 0, indicating that no events have yet occurred. If an event flag is no longer required it can be cleaned up with a call to

This takes three arguments. The first identifies a particular event flag. The second is some combination of bits, indicating which events are of interest. The final argument should be one of the following.

Will block until all the specified event bits are set. The event flag is not cleared when the wait succeeds, in other words all the bits remain set.

The call will block until at least one of the specified event bits is set. The event flag is not cleared on return.

The call will block until all the specified event bits are set, and the entire event flag is cleared when the call succeeds. Note that if this mode of operation is used then a single event flag cannot be used to store disjoint sets of events, even though enough bits might be available. Instead each disjoint set of events requires its own event flag.

The call will block until at least one of the specified event bits is set, and the entire flag is cleared when the call succeeds.

Normally blocks until the required condition is satisfied. It will return the value of the event flag at the point that the operation succeeded, which may be a superset of the requested events. If

Can be used to clear one or more bits in the event flag. This can be called from a producer when a particular condition is no longer satisfied, for example when the user is no longer pressing a particular button. It can also be used by a consumer thread if

Then typically some additional synchronization such as a mutex is needed to prevent multiple threads consuming the same event. Two additional functions are provided to query the current state of an event flag.

These exhibition flags, event flags and promotional flags are highly mobile systems to promote your graphic display and fabric flags. No need for planning permission, and these flags ideal for outdoor and indoor display events.

Base folds for easy transportation and storageThe GiantPole is an event flag system that is ideal for outdoor or indoor advertising. The event flag system stands 17ft 8in tall and is designed to fly a 43.3"w x 155"h flag. This puts the bottom of the custom flag over 4-3/4ft above the ground. This event flag system, like other outdoor banner stands and outdoor display systems can be filled with sand or water, for stability in winds up to 31mph. With this event flag system the advertising flag is still visible due to the flag arm, even in light winds or with no wind. The flag arm is attached to the top of the telescoping flagpole and extends horizontally along the top of the advertising flag. The event flag system comes with an aluminum telescopic flagpole that collapses down for transportation and storage. The telescoping flagpole also makes setup a breeze. The advertising event flags can be attached at ground level and then each section of the flagpole can be raised up and locked into position. Because the telescoping pole is made of aluminum, it is light enough to be raised by one person. The event flag system has a four leg support that attaches to the base to distribute wind loads. The base also folds for easy transportation and storage between events. A hanging weight on the bottom grommet of the flag keeps advertising event flag extended and does not allow the flag wrap around the pole. The flag arm and flag are free to rotate with the wind. This ability to rotate 360 degrees provides attention grabbing motion and allows the event flag system to withstand greater winds. This allows the the advertising event flags to move to the position with the least wind resistance. This allows the advertising event flags to fly in stronger winds than other event flag systems like outdoor banner stands and advertising signs. Included in this set is the GiantPole event flag stand and two carrying bags for travel. One of the bags is designed to hold the telescoping pole, support legs and flag attachment hardware, while the other stores the folding base.

Wait on all of a group of event flags. An event flag cluster can be accessed by any task on a CPU. when the utilities are built with the "VxMP" CPP symbol defined, clusters can be shared across CPUs. Event flag clusters are implemented by storing the name of the cluster in the named object database (which is implemented using the system symbol table or the VxMP shared name database). The value of the named object is the address of a cluster structure allocated on the heap (or from shared memory under VxMP). The cluster structure contains an N-bit long word whose bits represent event flags 0 through N-1 of the cluster. The structure also contains the IDs of two semaphores (shared under VxMP). a mutual exclusion semaphore used to prevent multiple tasks from modifying the event flags at the same time, and a change semaphore used to signal waiting tasks that the state of the event flags has changed. Before accessing the event flags in a cluster, a task must "create" the cluster. #include "ef_util. h" -- Event flag definitions. EfCluster cluster.. ef_create ("name", 0, debug, &cluster). The first task to call

Appended to it before being entered into the named object database. Event flags can be set or reset by calling

For example, the following call simultaneously sets event flags 2 and 4 and clears event flags 3 and 5. long flags = 0x us. C. long state = 0x us... ef_change (cluster, flags, state). Alternatively, you can use the macros

). ef_set (cluster, 0x us. ). -- Set event flags 2 and 4. ef_clear (cluster, 0x us. ). -- Clear event flags 3 and 5. The current state of the events flags in a cluster can be polled with the

Function. The following example tests if event flag 2 is set and 3 is clear. long state.. ef_read (cluster, &state). if ((state & 0x us. ) && -- Event flag 2 is set? !(state & 0x us. )) -- Event flag 3 is clear?. There are two means of waiting on event flags. First, a task can wait for

Of the selected event flags to reach the desired states. In the following example, the task waits for event flags 2 and 4 to be set

Event flags 3 and 5 to be clear. long flags = 0x us. C. long state = 0x us... ef_wait_all (cluster, flags, state, -1.0). Second, a task can wait for

Of the selected event flags to reach their desired states. For example, the following call suspends its task until event flag 2 or 4 is set

Event flag 3 or 5 is clear. long flags = 0x us. C. long state = 0x us... ef_wait_any (cluster, flags, state, -1.0). The event flag waits are implemented by suspending the task on the cluster's change semaphore. Whenever the event flags are modified, the change semaphore is flushed, awakening any task waiting on the event flags in the cluster. These tasks then check the state of the flags. if the flags are not yet in the desired state, the tasks suspend on the semaphore again. When a task terminates, it should "delete" the cluster. ef_delete (cluster). The cluster isn't actually deleted from the system until the last process using it deletes it.

Richard Neitzel of the National Center for Atmospheric Research wrote a C++ class (available in the VxWorks archive there) that uses somewhat the same approach to implementing event flags. There is a possible timing problem in the

Functions. These functions check the event flags immediately before waiting on a cluster's change semaphore. Suppose a task were interrupted after checking the flags but before waiting on the change semaphore. If the "signalling" task manages to change the event flags and flush any tasks waiting on the change semaphore before the first task has a chance to resume execution, the first task will miss the change and potentially wait forever (if another change never comes). To catch one such "straggler", the signalling task signals the change semaphore after flushing any pending tasks. However, could there be more than one straggler? The name/cluster mappings and reference counts are stored in the named object database (see

5/1/2008 - PosterGarden has introduced its very own line of Event Flags, utilizing the same unique imaging process that gives its Event Tents a true edge in brilliance and affordability. Lightweight, durable, and noticeable, PosterGarden’s exclusive new Event Flags are printed with the company’s full-color dye-sublimation process, which lets customers print in any color or pattern they choose and with any custom graphic they want. The process ensures that graphics are bright, brilliant, and eye-catching. “The dye-sublimation process really lends itself well not only to our Event Tents, but now to our Event Flags as well,” says Michael Rigby, PosterGarden’s Director of Product Development. “These vibrant colors and graphics make our flags nearly impossible to miss. They’ll make people stop and turn their heads, which is what our customers want.” Available in three different sizes and with a range of optional bases, PosterGarden’s Event Flags are great complements to any indoor or outdoor display. They are also bold and strong enough to stand on their own. In addition to the dye-sublimation printing process, the new flags are printed on PosterGarden’s PolySilk Fabric, a 3oz polyester fabric durable enough for outdoor use yet light enough to impart a soft, flowing look.

The Question is. I need some help on Mailboxes. Process A creates a read/write mailbox with I/O channel defined in variable chanA. Process B creates a read/write mailbox with I/O channel defined in variable chanB. Process A does a sys$qio(0, chanA, IO$_WRITEVBLK,.. Process B issues a read sys$qio(efn, chanB, IO$_READVBLK what I don't understand is how Process B can read the stuff written by Process A as they both have different event flags and channle numbers !! My code works I just can't understand what is happening.

The Answer is. Process event flags and process channels are process-specific constructs, and have no relation to the process event flags and the process channels used in other processes. An example of using mailboxes is available at. The OpenVMS Wizard would recommend one reader process per mailbox, with zero or more processes writing to the mailbox. This approach completely avoids the "turn-around" problems that are involved with half-duplex communications via a single mailbox. Do not use event flag zero. Allocate the required event flags using lib$get_ef or (if you are on a sufficiently recent OpenVMS version, you can use the "do not care" event flag EFN$C_ENF (defined in $EFNDEF/EFNDEF. H). Read up on $qiow and $synch. Always explicitly synchronize I/O completion -- see topic (1661) for a list of some common programming errors and various programming suggestions.

Our sail flags and flag poles are suitable for everyone, whether you are looking for banner stands, indoor displays, advertising flags or outdoor displays to promote your business or need extra impact at special events. If you want a competitive, instant high impact marketing product then look no further, simply contact us for a quotation.

Our unique flag pole system uses a purpose built telescopic PVC coated steel banner pole. The pole has an upper arm, which displays the flag whatever the weather conditions. The arm rotates through 360 degrees, so the flag never furls around the pole. The pole is fully telescopic. It can be transported easily and when in use can be extended from 5 to 10 (1.5m to 3m). Sailflags are ideally suited for outdoor advertising, promotions, events and exhibitions and can be supplied with your logo, company or organisation name, or any message you choose. This flag system has been tested on Cornish beaches in 25 knot winds.

----Original Message----- From. Bill Crowe [] Sent. November 16, 2007 4.03 PM To. ostech-core_os Subject. Re. RE. Event Flags Support I apologize for being so vague. I might have already found the answer to my initial question, but this is what I meant. Is there a way for a thread to pend on multiple conditions being met? So, other threads would post events and the pending thread would unblock when all of its specified conditions are met. I haven't found anything that does exactly what I want, but obviously I could write a wrapper that used condition variables. Just didn't want to reinvent the wheel. The condition variable is exactly what you want. An arbitrary set of data that you determine to release the execution. The other thing that may work for you are the barriers. Slightly different but depending on what you want to do it might be the thing for you to use. Hope this helps, Thomas

When I execute this code fragment on a CGEventRef, I get a meaningful result. (CGEventGetFlags(eventRef) kCGEventFlagMaskNonCoalesced) But when I execute this code fragment on a CGEventSourceRef, my program goes into some sort of infinite loop that I can't debug. ((CGEventSourceFlagsState(CGEventSourceGetSourceStateID(eventSourceRef))) kCGEventFlagMaskNonCoalesced) The same issue exists for the other flags, such as kCGEventFlagMaskNumericPad. I created the event source in question using the CGEventCreateSourceFromEvent() function in an event tap callback function, and the event source state ID is 1 (kCGEventSourceStateHIDSystemState). Will I be able to read these flags from the event source if I authenticate or run as root?

Hi Tom, I strongly believe that the messaging, besides some of the base header, deriving from GSMPv3 are of little use. The approach you should consider is along the lines of the Design Team proposal for multicast control. I understand that an updated proposal from them is imminent (must be next week at the latest), but you can observe and follow the concept followed in the previous one. In more detail. - Define message types which allow re-use across applications - Define common TLV and wrapper TLVs used in messages. In particular the flag field and result code ANCP inherited from GSMP in the base header seem to be particularly unwieldy, and I would encourage limiting their use or re-defining in a manner that does not cause compatibility issues with existing ANCP implementations. Could you share with us the events and flow control requirements that you see? Regards, Woj. -----Original Message----- From. ancp-bounces at ietf. org [mailto.ancp-bounces at ietf. org] On Behalf Of Tom Taylor Sent. 21 June 2008 01.20 To. ancp at ietf. org Subject. [ANCP] Events and event flags I'm in the process of trying to define an extension to ANCP to cover a multicast use case that isn't explicit in the framework. I need to define several events (e. g. to request more multicast bandwidth). Events seem to be tied closely to event flags and flow control flags in GSMPv3, which puts a sharp limit on the number of possible events due to limited flag field lengths. Has this been thought through in ANCP? What is the strategy, if any, for defining new events?

Hello, I think that this is the perfect solution for the event flags - to have a function that tracks the event flags. I don't know how to say it, but this is just what I wished from the event flags from their beginning. One of the reason not to use very often event flags in current SALVO was the limited set of possible logical operation over them. With the user defined function you make event flags extremely powerful and in the same time flexible. Excellent.This will make possible for example to track pins of the uP, variables, counters,.. everything. Well, from other side you should keep in mind that this will increase the kernel and maybe it will slow down the performance. Best regardsLuben

I use event flags almost exclusively for my inter-task communications. My usage paradigm is always signal a single bit, wait on multiple bits. Each of the waited-on bits has an individual meaning. I haven't had any need to assign meaning to combinations of bits. I don't know if that's a common usage scenario for other folks. In other words, I'm happy with the API as it is now.

The Question is. I need some help on Mailboxes. Process A creates a read/write mailbox with I/O channel defined in variable chanA.

Make something happen every frame The framerate of a Flash (or Director) application provides a very convenient timing mechanism to trigger repeated actions such as animating by code. It is also useful for checking the value of a button, sensor, mouse position, or implementing any system of tracking the current state of things. To make a movieclip animate every frame, we apply a standard event handler to the movieclip with the onClipEvent method. In this example, we rotate the movieclip by 10 degrees every frame.

A system for communicating in code - one part of the code signals another part of the code Variables can be used in code as a way for one part of the code to communicate with another part of the code. These signaling variables are often called Flags, because they are used like the flags on ships are used to communicate information to other ships (n. b. in both shipping and programming a more formal name for this signaling is the semaphore). For example, a button can set a flag variable to be true or false. Separately, a movieclip can check the value of this flag variable every frame (using the above enterframe event). If the movieclip finds the flag to be set to true using an if statement, the movie clip can rotate by 10 degrees, otherwise it does nothing.

Enterframe_flag Code on the first frame of the timeline. create and initialize the flag variable var turningFlag = false. Code on the button. toggle the flag value between true and false on (release) { if (_root. turningFlag == false) { _root. turningFlag = true. } else { _root. turningFlag = false. } } Code on the square movieclip. check the value of the flag, rotate if it is true onClipEvent(enterFrame) { if (_root. turningFlag == true) { this._rotation +=10. } }

Interface_scale. fla Code on the movieclip event load. initialize the scale, size flag, and scale transition flag onClipEvent(load) { this._xscale = 20. // initial x scale this._yscale = 20. // initial y scale this. size = 20. // the current state this. clicked = false. // to indicate if the user clicked } Code on the movieclip event enterframe. check to see if the user clicked, if so, scale up/down by 20% every frame using += 20 until we reach the maximum or minimum scale (check with an if statement), then shut off the scaling by reseting the clicked flag. Switch the timeline frame as appropriate for the new state using gotoAndStop. Toggle the size flag appropriately.

Code on the movieclip event release. when the user clicks, set the clicked flag to true so the scaling will start. on (release) { this. clicked = true. }

Right, I'd love to give an explanation as to why and how stuff works, but I haven't got a clue why, it just seems to work, so I use it. ^^ Anywho, comparing a unitflag to a filter is done as follows. CombatLog_Object_IsA(unitflag, filter) Creating is a filter is done like this. filter = bit. bor(unitflags you want to to match) You can find the different unitflags here. . Not that they're all globals. Every unitflag has one flag from Affiliation, one from Reaction, one from Ownership, one from Unit type and any number from Special cases. Creating a filter for your pet would be. MyPetFilter = bit. bor(COMBATLOG_OBJECT_AFFILIATION_MINE, COMBATLOG_OBJECT_REACTION_FRIENDLY, COMBATLOG_OBJECT_TYPE_PET, COMBATLOG_OBJECT_CONTROL_PLAYER) I hope this helps you a bit, if not, just wait for someone to come by that does know what he's doing. ^^

Actually, I'm trying to check whetever an aura removed was removed from a pet, which should I use then? destflags or sourceflags? Also, are you sure CombatLog_Object_IsA() returns true/false? I've noticed many WoW lua functions described in the wiki returning 1 or nil. But I'll try that.)

An event flag group is a synchronization object represented by a long-word structure. every available bit in such word can be used to map a user-defined event flag. When a flag is set, the associated event is said to have occurred. Xenomai tasks and interrupt handlers can use event flags to signal the occurrence of events to other tasks. those tasks can either wait for the events to occur in a conjunctive manner (all awaited events must have occurred to wake up), or in a disjunctive way (at least one of the awaited events must have occurred to wake up).

Bind to an event flag group. This user-space only service retrieves the uniform descriptor of a given Xenomai event flag group identified by its symbolic name. If the event flag group does not exist on entry, this service blocks the caller until a event flag group of the given name is created.

The address of an event flag group descriptor retrieved by the operation. Contents of this memory is undefined upon failure.

Is the address of a memory location which will be written upon success with the previous value of the event group before the flags are cleared.

Create an event group. Event groups provide for task synchronization by allowing a set of flags (or "events") to be waited for and posted atomically. An event group contains a mask of received events. any set of bits from the event mask can be pended or posted in a single operation. Tasks can wait for a conjunctive (AND) or disjunctive (OR) set of events to occur. A task pending on an event group in conjunctive mode is woken up as soon as all awaited events are set in the event mask. A task pending on an event group in disjunctive mode is woken up as soon as any awaited event is set in the event mask.

The event group creation mode. The following flags can be OR'ed into this bitmask, each of them affecting the new group.

Unbind from an event flag group. This user-space only service unbinds the calling task from the event flag group object previously retrieved by a call to rt_event_bind().

If you use Alpha OpenVMS event flags in your source code, make sure none of them are numbered 1-18 before compiling the code for use against the Oracle Server. Event flags 1-18 are reserved for the Server.

Event flags signal the completion of synchronous and asynchronous events in Alpha OpenVMS, such as disk I/O, terminal I/O, timers, the return of system and user information, lock acquisition, and user interrupts. Oracle9

Prevents asynchronous events from interfering with synchronous events by overwriting their event flags. This may increase the reliability of Oracle9

Makes hard-coded references to event flags 1 - 18. All of these event flags except flags 1 and 5 are tied to specific asynchronous events within Oracle9

And can also be used by application programmers. SYS$GETEF() is not used for these event flags. SQL*Net version 2 also uses additional event flags, which it gets dynamically from SYS$GETEF() calls from the second event flag group that ranges from 32-63. Make sure that you check the availability of any event flags you use in this range.

Within TAE library subroutines under VAX/VMS, event flags for asynchronous events are allocated using the VMS LIB$GET_EF subroutine. When such event flags are no longer needed, they are deallocated using the LIB$FREE_EF subroutine. There is one event flag for synchronous events. it is allocated automatically by TAE, using LIB$GET_EF, at the start of the application. Application programs that use event flags should also use the LIB$GET_EF and LIB$FREE_EF routines to avoid using the same event flags as the TAE library.

Array to reduce code size as in the following example. for (i = 0. i 4. i++) { Vin[i] = 0.0. pvPut (Vin[i]). } We also have a shorthand method for assigning channels to array elements. assign Vin to { {unit}1, {unit}2, {unit}3, {unit}4 }. Similarly, the monitor declaration may be either by individual element. monitor Vin[0]. monitor Vin[1]. monitor Vin[2]. monitor Vin[3]. Alternatively, we can do this for the entire array. monitor Vin. And the same goes when synchronizing with event flags (See Synchronizing State Sets with Event Flags) and queuing monitors (See Queuing Monitors). SNL arrays are really quite powerful. Double subscripts offer additional options. double X[2][100]. assign X to {apple, orange}. The declaration creates an array with 200 elements. The first 100 elements of

State sets within a state program may be synchronized through the use of event flags. Typically, one state set will set an event flag, and another state set will test that event flag within a

Statement may also be used to associate an event flag with a control system variable that is being monitored. In that case, whenever a monitor is delivered, the corresponding event flag is set. Note that this provides an alternative to testing the value of the monitored channel and is particularly valuable when the channel being tested is an array or when it can have multiple values and an action must occur for any change. This example shows a state set that forces a low limit always to be less than or equal to a high limit. The first

Clause fires when the opposite situation occurs. double loLimit. assign loLimit to demo.loLimit. monitor loLimit. evflag loFlag. sync loLimit loFlag. double hiLimit. assign hiLimit to demo.hiLimit. monitor hiLimit. evflag hiFlag. sync hiLimit hiFlag. ss limit { state START { when ( efTestAndClear( loFlag ) loLimit hiLimit ) { hiLimit = loLimit. pvPut( hiLimit ). } state START when ( efTestAndClear( hiFlag ) hiLimit loLimit ) { loLimit = hiLimit. pvPut( loLimit ). } state START } } The event flag is actually associated with the SNL variable, not the underlying control system variable. If the SNL variable is an array then the event flag is set whenever a monitor is posted on any of the control system variables that are associated with an element of that array.

Clause nor associating the channel with an event flag and then testing the event flag can guarantee that the sequence is aware of all monitors posted on the channel. Often this doesn't matter, but sometimes it does. For example, a variable may transition to 1 and then back to 0 to indicate that a command is active and has completed. These transitions may occur in rapid succession. This problem can be avoided by using the

Clause, as in. when (pvConnectCount() pvAssignCount()) { } state disconnected When using dynamic assignment, you should wait for the newly assigned variables to connect, as in. when (pvConnectCount() == pvAssignCount()) { } state connected when (delay(10)) { } state connect_timeout Note that the connection callback may be delivered before or after the initial monitor callback (the PV API does not specify the behavior, although the underlying message system may do so). If this matters to you, you should synchronize the value with an event flag and wait for the event flag to be set before proceeding. See See Synchronizing State Sets with Event Flags for an example.

Flags4events. com is a division of Ultra Sport Europe - an extreme sports equipment distributor selling a wide range of products in tough and competitive markets. Finding that the use of promotional flags frequently delivered a marketing edge, there followed the development of a concise range of flag products.

The giant pole is a new design of flagpole that is ideal for outdoor events, conferences, sports events. Portable marketing solution. The telescopic aluminium flag pole fits into a plastic moulded base that can be filled with water for stability. The flag is held on using a top bar and rings. It is free to rotate according to the wind direction. Giantpoles have dozen of different uses. They offer high visibility at open air events, in front of exhibition halls, service stations shopping malls or department stores. Giantpoles are easy to handle and to install. The water filled base and rotating top arm make them very stable It only takes a couple of minutes to put up the giantpole. No holes to dig just fill the base with water. Tested to the European TV standard.

Yes, XtAppAddInput() does work on OpenVMS. The MIT definition of the X Windows call XtAppAddInput() includes platform-specific arguments. On platforms where C is the typically the primary programming language for the platform, the file descriptor mask is one of the arguments to the XtAppAddInput() call. On OpenVMS, the platform-specific arguments to this call include an event flag and an IOSB, as these are the traditional OpenVMS constructs used to synchronize the completion of asynchronous operations. While it would be easier to port non-OpenVMS C code that calls XtAppAddInput() over to OpenVMS if the arguments included the C file descriptor, this would make the call unusable from other OpenVMS languages, and would make it extremely difficult to use OpenVMS features such as ASTs and sys$qio calls. One restriction on the event flag. the event flag chosen must be from event flag cluster zero. When using the traditional lib$get_ef and lib$free_ef calls to allocate and deallocate event flags, you must first explicitly call lib$free_ef to free up some event flags in event flag cluster zero. Please see the event flag documentation for specific details on these calls and for specific event flags that can be freed in event flag cluster zero. Here is some example code that covers calling this routine on OpenVMS.

There is an effective work around to do this by making an artificial ticker for each stock and then using the Foreign() call for testing. For example, for IBM create a ticker IBM_Flags Put your info into the various price and volume field. That will give you 6 data items. If you want 10 fields, divide the O, H, L, C fields in half using the decimal point. It is easy to use AB's Fraction and Integer calls to get what you want. If you need a lot of data fields, you can pack the data into each digit of the price and volume fields. And then use AB's Fraction and Integer calls with appropriate division and multiplication to get the data items separated. Theoretically you should be able to get 6 digits in the price fields and 9 in the volume and OI fields. But for safety you can use 5 from each. Also, you can pack 9 digits into the volume and oi fields, but you can only extract 6 digits since AB usings changes the data in these fields to decimal data (only 6 significant digits) to do the multiplication and division functions. Even with just using 5 in each of the 6 regular fields, that gives you 30 data fields, each with a range of 0 to 9. b --- In amibroker@xxxx, us. @xxxx wrote. Some thoughts from a new user. What is missing in today's EOD TA packages is the lack of storing events with the daily data and the ability to use this information in formulae. These events do not need to take up much space. In fact they can be bit fields (Yes/No, True/False values). Using only 4 bytes for this would allow us such 32 independent event flags. These event flags could be picked from a predefined list, or be user-defined. For example. COMPANY_CRISIS MARKET_CRISIS BAD_NEWS GOOD_NEWS BAD_RATINGS GOOD_RATINGS STOCK_SPLIT ER_BEFORE_MARKET_OPEN ER_DURING_MARKET_OPEN ER_AFTER_MARKET_OPEN ER_BELOW_EXPECTATIONS ER_MEETS_EXPECTATIONS ER_ABOVE_EXPECTATIONS. Such events have an impact on the price. And they answer the question of (dramatic) price changes on a specific day(s). By having this (optional) information with each EOD data one could develop better strategies/programs by filtering any of the (un)wanted events. I hope, one day AmiBroker will have this feature implemented.-) (. or is it already possible?.-)

Hi Jeff. Event flag processing is a "special case" and is a bit different from all the other event types. Specifically, if, say, a binSem is signaled, since the binSem's event queue is a priority queue and only a single task can be at the head of a queue (even if multiple tasks are waiting the binSem), then just that one task is made eligible when the binSem is signaled. eFlags are different because of the fact that multiple tasks can wait on individual bits of an eFlag -- i. e. there is no real sense of priority associated with tasks waiting an eFlag, because a change in any bit must be seen by every task that's watching that bit. Therefore, Salvo has to make all tasks that wait an eFlag eligible whenever the eFlag is signaled. The now-eligible tasks all retain their priorities, of course, with regard to when they'll actually run. So, yes, the FAQ is talking about all event types except eFlags. eFlags behave slightly differently, and one sees this when more than one task waits a particular eFlag us.

I was reading the Salvo manual, v3.2.2, and have the following question about event flags.In the notes for OSSetEFlag() (p.344), it states that all tasks waiting an event flag are made eligible by forcing any zeroed bits to one. However, in the FAQ (p. 235) 'when an event occurs and there are tasks waiting for it, which task(s) become eligible?', it states that only a single task will become eligible. Which statement is correct?It sounds like the FAQ is only talking about semaphores and not event flags. Is that the case?thanks, Jeff

Repeat victimization has recently featured prominently in crime reduction research, especially in the UK. Crime prevention efforts which focus on repeats have enjoyed some success. Yet little is known about what generates repeat victimization. While this remains the case, the scope for crime reduction through the prevention of repeated events against the same target will be limited. There is general agreement about the potential relevance of two intertwined theoretical causes, namely event dependence (where the crime event boosts the probability of repetition), and heterogeneity (where the crime event flags an enduring risk, which enduring risk makes repetition likely). This paper attempts to disentangle the effects of event dependence and heterogeneity on repeat personal victimizations across three interviewing periods using the 1994 National Crime Victimization Survey. We employ a (fixed effects random intercept) multilevel model of personal crime counts incorporating individual and household characteristics as well as lifestyle and prior non-victimization of individuals clustered within households. Our results show that victimization by personal crime, especially over successive time periods, is partly due to measured heterogeneity. Personal crimes experienced by members of the same household are moderately but persistently correlated. This suggests that unmeasured heterogeneity is also implicated in period-to-period repetition of personal crime. The combined effects of unmeasured and measured heterogeneity do not exhaust the predictivity of prior for subsequent victimization, meaning that a degree of event dependence is involved.

The National Colonial Flag Foundation, creators of the Healing Field program, is honored to sanction the Healing Field® “Flags of Remembrance” event hosted and presented by the Exchange Clubs of Murfreesboro as part of the national program this event will display 1,500 US flags waving proudly atop 8-foot poles. This moving temporary memorial will pay tribute to those heroes who have paid the ultimate sacrifice for our freedom. With the help of the entire community, the grassy field on Medical Center next to Belk’s will be transformed into a sea of red, white and blue when hundreds of volunteers gather with their families to set up the flags for the three-day memorial event from May 23 – 25, 2009. To volunteer call Don Wright us. The flags will be set on a grid in perfect rows and columns similar to Arlington National Cemetery and each flag will bear the name of a brave man or woman who has given their life, served in the military or is currently in harm’s way in the war on terror. On the final day, May 25th, Memorial Day at sundown the memorial event will end with a patriotic ceremony, a prayer and the playing of “Taps”.Flags are available for sponsorship for $30 each to be taken home and flown proudly to continue the tribute. Event updates, donations and corporate sponsorships are also being accepted online at www. healingfield. org/murfreesboro or at the time of the event. Flags can be dedicated in honor or memory of a loved one. The proceeds from the event will benefit the programs of the local Exchange Clubs and the Exchange Club Family Center. Organizers here at the national headquarters for the Colonial Flag Foundation, Healing Field programs are honored to work with the leaders from Exchange Clubs of Murfreesboro as they bring this amazing and healing experience to the community as everyone unites for a greater purpose.

By. ItsGood on 2/6/09 Phil, the city planning commission and council has changed the sign ordinance to allow 24 square feet of flags, and multiple flags for a temporary event. It is my understanding the flags for this special event will be 3' x 5' on 8' tall poles.

In OpenVMS Alpha Version 7.0 and later, with few exceptions a blocking system service call is thread synchronous---that is, only the calling thread is blocked. The exceptions are services that do not block in user mode and services that set common event flags. (See also Section B.12.8.) When a thread calls a system service that must block, the OpenVMS scheduler makes an upcall to allow the Threads Library to schedule another user thread to execute. Therefore, only the calling thread is blocked, all other threads are unaffected, and the process continues running. When the service completes, the thread is awakened by means of another upcall, and the Threads Library schedules it to run again at the thread's next opportunity. This applies to all W forms of system services, for example, $QIOW, $END_TRANSW, and $GETJPIW. Additionally, this applies to the following event flag services. $WAITFR, $WFLAND, and $WFLOR.

All event flags are shared by all threads in the process. Therefore, it is possible for different threads' use of the same event flag to cause interference. If two threads use the same event flag in calls to different system services, whichever service completes first will cause both threads to awaken, even though the other service has not completed. This situation can be resolved by specifying an I/O status block (IOSB) for those system services that use them. When an IOSB is present, the blocked thread will not be awakened when the event flag is set, unless the IOSB has also been written. A Threads Library process is rarely in LEF state. In general, instead of blocking for an event flag wait, the Threads Library schedules another thread to be run. However, if no threads are available, the Threads Library schedules a null thread, which places the virtual processor in HIB state until it is needed to execute a thread.

If a thread calls a system service that uses a common event flag, the calling thread's virtual processor blocks until the wait is satisfied. (That is, no upcall is made to the OpenVMS kernel to schedule another thread.) On a uniprocessor, such a system service call will most likely cause all threads in the process to block.

By request, I added support for events spanning multiple days by adding an "End Date" field to the Add Event form. Also, on every event/venue/user, you'll now see a Flag for Review link. Please use this link to report any duplicate/fake events and abusive users, and I'll take care of them. Thanks for your help.

A common event flag cluster is a set of 32 event flags that enable cooperating processes to post event notifications to each other. Event flags in the cluster can be set or cleared to indicate the occurrence of an event. All event flags are contained within clusters of 32 event flags, and each process has access to four clusters (numbered 0 through 3). Two of the clusters are local to a single process. Event flag clusters 2 and 3 are called common event flag clusters and are used for interprocess synchronization. A subject may be associated with up to two common event flag clusters. Each common event flag in a cluster is referenced by an event flag number.

The name of the object is whatever character string was supplied as an argument to the Associate Common Event Flag Cluster system service ($ASCEFC). Remember that common event flag cluster names are qualified by your UIC group number.

Gives a process the right to establish an association with the named cluster so the process can access event flags.

Gives a process the right to mark a permanent event flag cluster for deletion with the Delete Common Event Flag Cluster ($DLCEFC) system service. The actual deletion occurs once all processes disassociate from the cluster.

The common event flag cluster class provides one template profile. Although the template assigns an owner UIC of [0,0], this value is only temporary. As soon as the object is created, the operating system replaces a 0 value with the value in the corresponding field of the creating process's UIC.

When the process creating the common event flag cluster supplies a prot argument to $ASCEFC that has a value of 1, then the system modifies the template so the process UIC is the owner, and the protection code denies group access.

Creation of a permanent common event flag cluster requires the PRMCEB privilege. This privilege also grants delete access for permanent clusters.

This command may be used to manually set and event flag within the ATwish program. Its principle use is as a debugging and development tool, but programmers may find it useful for setting event flags within the images that they run as a subprocess or for prematurely triggering the time event handler. *** at_setef should not be used in public release software ***

Flags are a great choice for an event backdrop because they are symbolically loaded images. Flags motivate people. In other words, people don't just see flags. They see a country, company, or organization. And, people see everything they associate with that image - people, experiences, and feelings - all things that will motivate your audience to action. When combined with warm lighting, there is nothing more effective than a powerful flag display.
