MPSetEvent

MPSetEvent
Header:	Multiprocessing.h		Carbon status:	Supported

Merges event flags into a specified event group.

OSStatus MPSetEvent (
    MPEventID event, 
    MPEventFlags flags
);

event: The ID of the event group you want to set.
flags: The flags you want to merge into the event group.

function result: A result code.

DISCUSSION

The flags are logically ORed with the current flags in the event group. This procedure is an atomic operation to ensure that multiple updates do not get lost. If tasks are waiting on this event group, the first waiting task is unblocked.

Note that you can call this function from an interrupt handler.

Also see the function MPWaitForEvent.
