Defines
#define	DISPATCH_SOURCE_TYPE_DATA_ADD   (&_dispatch_source_type_data_add)
	A dispatch source that coalesces data obtained via calls to dispatch_source_merge_data().
#define	DISPATCH_SOURCE_TYPE_DATA_OR   (&_dispatch_source_type_data_or)
	A dispatch source that coalesces data obtained via calls to dispatch_source_merge_data().
#define	DISPATCH_SOURCE_TYPE_MACH_SEND   (&_dispatch_source_type_mach_send)
	A dispatch source that monitors a Mach port for dead name notifications (send right no longer has any corresponding receive right).
#define	DISPATCH_SOURCE_TYPE_MACH_RECV   (&_dispatch_source_type_mach_recv)
	A dispatch source that monitors a Mach port for pending messages.
#define	DISPATCH_SOURCE_TYPE_PROC   (&_dispatch_source_type_proc)
	A dispatch source that monitors an external process for events defined by dispatch_source_proc_flags_t.
#define	DISPATCH_SOURCE_TYPE_READ   (&_dispatch_source_type_read)
	A dispatch source that monitors a file descriptor for pending bytes available to be read.
#define	DISPATCH_SOURCE_TYPE_SIGNAL   (&_dispatch_source_type_signal)
	A dispatch source that monitors the current process for signals.
#define	DISPATCH_SOURCE_TYPE_TIMER   (&_dispatch_source_type_timer)
	A dispatch source that submits the event handler block based on a timer.
#define	DISPATCH_SOURCE_TYPE_VNODE   (&_dispatch_source_type_vnode)
	A dispatch source that monitors a file descriptor for events defined by dispatch_source_vnode_flags_t.
#define	DISPATCH_SOURCE_TYPE_WRITE   (&_dispatch_source_type_write)
	A dispatch source that monitors a file descriptor for available buffer space to write bytes.
Typedefs
typedef struct dispatch_source_s *	dispatch_source_t
	The dispatch framework provides a suite of interfaces for monitoring low- level system objects (file descriptors, Mach ports, signals, VFS nodes, etc.) for activity and automatically submitting event handler blocks to dispatch queues when such activity occurs.
typedef struct dispatch_source_type_s *	dispatch_source_type_t
	Constants of this type represent the class of low-level system object that is being monitored by the dispatch source.

Functions
dispatch_source_t	dispatch_source_create (dispatch_source_type_t type, uintptr_t handle, unsigned long mask, dispatch_queue_t queue)
	Creates a new dispatch source to monitor low-level system objects and auto- matically submit a handler block to a dispatch queue in response to events.
void	dispatch_source_set_event_handler (dispatch_source_t source, dispatch_block_t handler)
	Sets the event handler block for the given dispatch source.
void	dispatch_source_set_event_handler_f (dispatch_source_t source, dispatch_function_t handler)
	Sets the event handler function for the given dispatch source.
void	dispatch_source_set_cancel_handler (dispatch_source_t source, dispatch_block_t cancel_handler)
	Sets the cancellation handler block for the given dispatch source.
void	dispatch_source_set_cancel_handler_f (dispatch_source_t source, dispatch_function_t cancel_handler)
	Sets the cancellation handler function for the given dispatch source.
void	dispatch_source_cancel (dispatch_source_t source)
	Asynchronously cancel the dispatch source, preventing any further invocation of its event handler block.
long	dispatch_source_testcancel (dispatch_source_t source)
	Tests whether the given dispatch source has been canceled.
uintptr_t	dispatch_source_get_handle (dispatch_source_t source)
	Returns the underlying system handle associated with this dispatch source.
unsigned long	dispatch_source_get_mask (dispatch_source_t source)
	Returns the mask of events monitored by the dispatch source.
unsigned long	dispatch_source_get_data (dispatch_source_t source)
	Returns pending data for the dispatch source.
void	dispatch_source_merge_data (dispatch_source_t source, unsigned long value)
	Merges data into a dispatch source of type DISPATCH_SOURCE_TYPE_DATA_ADD or DISPATCH_SOURCE_TYPE_DATA_OR and submits its event handler block to its target queue.
void	dispatch_source_set_timer (dispatch_source_t source, dispatch_time_t start, uint64_t interval, uint64_t leeway)
	Sets a start time, interval, and leeway value for a timer source.
