| 6 | .Nm dispatch | |
| 7 | .Nd the dispatch framework | |
| 8 | .Sh SYNOPSIS | |
| 9 | .Fd #include <dispatch/dispatch.h> | |
| 10 | .Sh DESCRIPTION | |
| 11 | The dispatch framework allows blocks to be scheduled for asynchronous and | |
| 12 | concurrent execution via the core functions described in | |
| 13 | .Xr dispatch_async 3 and | |
| 14 | .Xr dispatch_apply 3 . | |
| 15 | .Pp | |
| 16 | Dispatch queues are the basic units of organization of blocks. Several queues | |
| 17 | are created by default, and applications may create additional queues for their | |
| 18 | own use. See | |
| 19 | .Xr dispatch_queue_create 3 | |
| 20 | for more information. | |
| 21 | .Pp | |
| 22 | Dispatch groups allow applications to track the progress of blocks submitted to | |
| 23 | queues and take action when the blocks complete. See | |
| 24 | .Xr dispatch_group_create 3 | |
| 25 | for more information. | |
| 26 | .Pp | |
| 27 | The dispatch framework also provides functions to monitor underlying system | |
| 28 | events and automatically submit event handler blocks to dispatch queues. | |
