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.
