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.
