dispatch(3) 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 submit- ted to queues and take action when the blocks complete. See dis- patch_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.
