Function Documentation

int add_timer (  unsigned int  tick, int(*)(int, unsigned int, intptr_t, intptr_t)  func, intptr_t  id, intptr_t  data )

Adds a timed callback. Example usage: add_timer(gettick_cache + 3000, some_func, id, 0); Returns: The assigned ID of this timer. Parameters: tick  The time when function will called in milisecond. func  The callback function. id  Specific id, usually the session data. data  The data to be passed to callback.

int add_timer_interval (  unsigned int  tick, int(*)(int, unsigned int, intptr_t, intptr_t)  func, intptr_t  id, intptr_t  data, int  interval )

Adds a timed callback that is called every a given interval. Returns: The assigned ID of this timer. Parameters: tick  The time when function will be called in milisecond. func  The callback function. id  The specific id of this timer. data  Data to be passed to callback. interval  The interval in milisecond.

unsigned int addtick_timer (  int  tid, int  added_tick )

Adds delay into a timer. Parameters: tid  The ID assigned for this timer. added_tick  The delay in milisecond.

int delete_timer (  int  id, int(*)(int, unsigned int, intptr_t, intptr_t)  func )

Deletes a timer. Returns: 0 on success, -1 if timer does not exist, -2 on failure. Parameters: id  The timer id. func  The callback function.

struct TimerData* get_timer (  int  tid  )

Gets the timer data. Returns: The timer data. Parameters: tid  The ID assigned for this timer. Todo: Remove from header declaration, it should not be used outside.
