Scheduler FunctionsScheduler Functions — Support for delayed or periodic execution of functions | |
Details
mon_sched_doit ()
void mon_sched_doit (void);
Calls all callbacks that have met their deadline.
mon_sched_cb ()
void (*mon_sched_cb) (void *ptr);
Prototype of schedulable functions.
| ptr : | Opaque pointer that will be passed to the function.
|
mon_sched_at ()
int mon_sched_at (mon_sched_cb cb,
void *data,
struct timeval *when);
Schedules a function to run once at the specified time.
| cb : | the function to schedule.
|
| data : | opaque data that will be passed to the function.
|
| when : | a struct timeval holding the deadline.
|
| Returns : | 0 if successful or an error code.
|
mon_sched_once ()
int mon_sched_once (mon_sched_cb cb,
void *data,
int delay);
Schedules a function to run once after a specified delay.
| cb : | the function to schedule.
|
| data : | opaque data that will be passed to the function.
|
| delay : | delay in milliseconds.
|
| Returns : | 0 if successful or an error code.
|
mon_sched_periodic ()
int mon_sched_periodic (mon_sched_cb cb,
void *data,
int freq);
Schedules a function to run periodically with the specified frequency.
| cb : | the function to schedule.
|
| data : | opaque data that will be passed to the function.
|
| freq : | frequency in milliseconds.
|
| Returns : | 0 if successful or an error code.
|
mon_sched_remove ()
int mon_sched_remove (mon_sched_cb cb,
void *data);
Removes a previously scheduled function. Both the cb and data arguments must
match what was given when the function was scheduled.
| cb : | the function that was scheduled.
|
| data : | opaque data to be passed to the function.
|
| Returns : | 0 if successful or an error code.
|
mon_sched_freq_mod ()
int mon_sched_freq_mod (mon_sched_cb cb,
void *data,
int freq);
Modifies the frequency of a fuction that was scheduled to run periodically.
| cb : | the function that was scheduled.
|
| data : | opaque data to be passed to the function.
|
| freq : | the new frequency in milliseconds.
|
| Returns : | 0 if successful or an error code.
|
mon_sched_done ()
void mon_sched_done (void);
Removes all scheduled functions and deallocates any internal resources held by
the scheduler.
