DESCRIPTION
A dispatch group is an association of one or more blocks submitted to dispatch queues for asynchronous invocation. Applications may use dis-
patch groups to wait for the completion of blocks associated with the group.
The dispatch_group_create() function returns a new and empty dispatch group.
The dispatch_group_enter() and dispatch_group_leave() functions update the number of blocks running within a group.
The dispatch_group_wait() function waits until all blocks associated with the group have completed, or until the specified timeout has
elapsed. If the group becomes empty within the specified amount of time, the function will return zero indicating success. Otherwise, a non-
zero return code will be returned. When DISPATCH_TIME_FOREVER is passed as the timeout, calls to this function will wait an unlimited amount
of time until the group becomes empty and the return value is always zero.
The dispatch_group_notify() function provides asynchronous notification of the completion of the blocks associated with the group by submit-
ting the block to the specified queue once all blocks associated with the group have completed. The system holds a reference to the dispatch
group while an asynchronous notification is pending, therefore it is valid to release the group after setting a notification block. The
group will be empty at the time the notification block is submitted to the target queue. The group may either be released with
dispatch_release() or reused for additional operations.
The dispatch_group_async() convenience function behaves like so:
void
dispatch_group_async(dispatch_group_t group, dispatch_queue_t queue, dispatch_block_t block)
{
dispatch_retain(group);
dispatch_group_enter(group);
dispatch_async(queue, ^{
block();
dispatch_group_leave(group);
dispatch_release(group);
});
}
RETURN VALUE
The dispatch_group_create() function returns NULL on failure and non-NULL on success.
The dispatch_group_wait() function returns zero upon success and non-zero after the timeout expires. If the timeout is
DISPATCH_TIME_FOREVER, then dispatch_group_wait() waits forever and always returns zero.
MEMORY MODEL
Dispatch groups are retained and released via calls to dispatch_retain() and dispatch_release().
FUNDAMENTALS
The dispatch_group_async() and dispatch_group_notify() functions are wrappers around dispatch_group_async_f() and dispatch_group_notify_f()
respectively.
