dispatch(3) BSD Library Functions Manual dispatch(3)
NAME
dispatch -- the dispatch framework
SYNOPSIS
#include <dispatch/dispatch.h>
DESCRIPTION
The dispatch framework allows blocks to be scheduled for asynchronous and
concurrent execution via the core functions described in
dispatch_async(3) and dispatch_apply(3).
Dispatch queues are the basic units of organization of blocks. Several
queues are created by default, and applications may create additional
queues for their own use. See dispatch_queue_create(3) for more informa-
tion.
Dispatch groups allow applications to track the progress of blocks sub-
mitted to queues and take action when the blocks complete. See
dispatch_group_create(3) for more information.
The dispatch framework also provides functions to monitor underlying sys-
tem events and automatically submit event handler blocks to dispatch
queues.
