.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.
