Ns_ScheduleDaily

Overview

Schedule a procedure to run once a day

Syntax

    int Ns_ScheduleDaily(
    	Ns_SchedProc				*proc,
    	void				*context,
    	int				flags,
    	int				hour,
    	int				minute,
    	Ns_SchedProc				*cleanup
    );

Description

The Ns_ScheduleDaily function schedules the procedure (proc) to be run once a day at the specified time (hour and minute).

The proc is the scheduled procedure that will be run once a day. It is a function that takes the context and id of the schedule procedure. The id can be used in the Ns_UnscheduleProc procedure to stop the procedure from being called again.

    typedef void (Ns_SchedProc) (void *context, int id);

The context is the context to pass to the scheduled procedure.

The possible flags are NS_SCHED_ONCE and NS_SCHED_THREAD. If you specify NS_SCHED_ONCE, the procedure will only be executed once on the specified day and time, and it will not be re-scheduled to execute again the next day. By default, the procedure is re-scheduled after every time it is executed.

If you specify NS_SCHED_THREAD, the procedure will run detached in a separate thread instead of using the one scheduled procedure thread used by all other scheduled procedures. You should use NS_SCHED_THREAD if the procedure will not return immediately. Note that if you use NS_SCHED_THREAD, and the procedure is still active the next time to run occurs, the next run is skipped instead of just delayed.

The hour can be an integer from 0 to 23, and the minute an integer from 0 to 59.

The cleanup procedure will be run once when the proc procedure is unscheduled.

Example

Run a procedure (MyProc) once in its own thread at 2:30 a.m.:

    Ns_ScheduleDaily(myProc, myCtx, NS_SCHED_ONCE | NS_SCHED_THREAD, 
2, 30, NULL)
