Stored procedures
Locks the current thread while waiting for the specified event to be opened.
Example
// Create an event
EventCreate("Let's go", eventAutomatic, eventClose)
// Run a first thread
ThreadExecute("Thread1", threadNormal, "Thread_First")
// Locks the current thread until the event is obtained
ThreadWaitSignal()
 
// Run a second thread
ThreadExecute("Thread2", threadNormal, "Thread_Second")
// Locks the current thread until the event is obtained
ThreadWaitSignal()
 
// Modifies the event to run the threads
EventChange("Let's go", eventOpen)
PROCEDURE Thread_First()
Trace(dbgInfo(dbgProcess) + " - ThreadSendSignal(threadMain)")
ThreadSendSignal(threadMain)
EventWait("Let's go")
Trace(dbgInfo(dbgProcess) + " - Event received")
PROCEDURE Thread_Second()
Trace(dbgInfo(dbgProcess) + " - ThreadSendSignal(threadMain)")
ThreadSendSignal(threadMain)
EventWait("Let's go")
Trace(dbgInfo(dbgProcess) + " - Event received")
Syntax
<Result> = EventWait(<Event> [, <Maximum duration>])
<Result>: Integer
  • 1 if the event was received by the thread,
  • 0 otherwise (maximum duration exceeded).
<Event>: Character string (with quotes), or AutomaticEvent or ManualEvent variable
  • Name of the event to wait for. If this event does not exist, it is automatically created with the default options (automatic mode) and closed.
<Maximum duration>: Optional integer or optional Duration
Maximum timeout in hundredths of a second.
  • If no event was received by the thread before the end of specified duration, <Result> is equal to False.
  • The time-out is endless if this parameter is not specified.
  • If this parameter is set to 0, <Result> corresponds to the status of the event, without waiting.
This parameter can correspond to:
  • an integer corresponding to the number of hundredths of a second,
  • a Duration variable,
  • Versions 23 and later
    the direct indication of duration (1 s or 10 ms for example).
    New in version 23
    the direct indication of duration (1 s or 10 ms for example).
    the direct indication of duration (1 s or 10 ms for example).
Remarks
You can end the execution of a thread even if it is locked in an endless wait for an event. Simply use ThreadStop.
