- .Sh NAME
- .Nm dispatch
- .Nd the dispatch framework
- .Sh SYNOPSIS
- .Fd #include <dispatch/dispatch.h>
- .Sh DESCRIPTION
- The dispatch framework allows blocks to be scheduled for asynchronous and
- concurrent execution via the core functions described in
- .Xr dispatch_async 3 and
- .Xr dispatch_apply 3 .
- .Pp
- 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
- .Xr dispatch_queue_create 3
- for more information.
- .Pp
- Dispatch groups allow applications to track the progress of blocks submitted to
- queues and take action when the blocks complete. See
- .Xr dispatch_group_create 3
- for more information.
- .Pp
- The dispatch framework also provides functions to monitor underlying system
- events and automatically submit event handler blocks to dispatch queues.
