dispatch_after(3)                       BSD Library Functions Manual                       dispatch_after(3)

NAME
     dispatch_after -- schedule blocks for deferred execution

SYNOPSIS
     #include <dispatch/dispatch.h>

     void
     dispatch_after(dispatch_time_t when, dispatch_queue_t queue, void (^block)(void));

     void
     dispatch_after_f(dispatch_time_t when, dispatch_queue_t queue, void *context,
         void (^function)(void *));

DESCRIPTION
     The dispatch_after() function submits the block to the given queue at the time specified by the when
     parameter.  The when parameter is a value created by dispatch_time() or dispatch_walltime().

     For a more detailed description about submitting blocks to queues, see dispatch_async(3).

CAVEATS
     Specifying DISPATCH_TIME_NOW as the when parameter is supported, but is not as efficient as calling
     dispatch_async().  The result of passing DISPATCH_TIME_FOREVER as the when parameter is undefined.

FUNDAMENTALS
     The dispatch_after() function is a wrapper around dispatch_after_f().
