Function Documentation

int fork_basic_timer	(	int	child_id,
		char *	desc,
		int	make_sock,
		timer_function *	f,
		void *	param,
		int	interval
	)

Forks a very basic periodic timer process, that just sleep()s for the specified interval and then calls the timer function. The new "basic timer" process execution start immediately, the sleep() is called first (so the first call to the timer function will happen <interval> seconds after the call to fork_basic_timer)

Parameters:

child_id

See also:: fork_process()

Parameters:

desc

See also:: fork_process()

Parameters:

make_sock

See also:: fork_process()

Parameters:

	f	timer function/callback
	param	parameter passed to the timer function
	interval	interval in seconds.

Returns:: pid of the new process on success, -1 on error (doesn't return anything in the child process)

Here is the call graph for this function:

int fork_basic_utimer	(	int	child_id,
		char *	desc,
		int	make_sock,
		utimer_function *	f,
		void *	param,
		int	uinterval
	)

Forks a very basic periodic timer process, that just ms-sleep()s for the specified interval and then calls the timer function. The new "basic timer" process execution start immediately, the ms-sleep() is called first (so the first call to the timer function will happen <interval> seconds after the call to fork_basic_utimer)

Parameters:

child_id

See also:: fork_process()

Parameters:

desc

See also:: fork_process()

Parameters:

make_sock

See also:: fork_process()

Parameters:

	f	timer function/callback
	param	parameter passed to the timer function
	uinterval	interval in mili-seconds.

Returns:: pid of the new process on success, -1 on error (doesn't return anything in the child process)

Here is the caller graph for this function:

int fork_local_timer_process	(	int	child_id,
		char *	desc,
		int	make_sock,
		struct local_timer **	lt_h
	)

Forks a separate timer process running a local_timer.h type of timer A pointer to the local_timer handle (allocated in shared memory) is returned in lt_h. It can be used to add/delete more timers at runtime (via local_timer_add()/local_timer_del() a.s.o). If timers are added from separate processes, some form of locking must be used (all the calls to local_timer* must be enclosed by locks if it cannot be guaranteed that they cannot execute in the same time) The timer "engine" must be run manually from the child process. For example a very simple local timer process that just runs a single periodic timer can be started in the following way: struct local_timer* lt_h;

pid=fork_local_timer_process(...., &lt_h); if (pid==0){ timer_init(&my_timer, my_timer_f, 0, 0); local_timer_add(&lt_h, &my_timer, S_TO_TICKS(10), get_ticks_raw()); while(1) { sleep(1); local_timer_run(lt, get_ticks_raw()); } }

Parameters:

child_id

See also:: fork_process()

Parameters:

desc

Parameters:

make_sock

See also:: fork_process()

Parameters:

lt_h

local_timer handler

Returns:: pid to the parent, 0 to the child, -1 if error.
