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
     information.

     Dispatch groups allow applications to track the progress of blocks submitted 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 system events and automatically
     submit event handler blocks to dispatch queues.
