Inheritance diagram for timer_driver:
Public Member Functions | |
| timer_driver () | |
| virtual | ~timer_driver () |
| IMPLEMENT_CLASS_NAME ("timer_driver") | |
| bool | set_timer (int duration, timed_object *to_invoke) |
| sets a timer to call "to_invoke" every "duration" milliseconds. | |
| bool | zap_timer (timed_object *to_drop) |
| removes the timer that was established for "to_drop". | |
| void | handle_system_timer () |
| invoked by the OS timer support and must be called by main thread. | |
Static Public Member Functions | |
| static timer_driver & | global_timer_driver () |
| the first time this is invoked, it creates a program-wide timer driver. | |
Multiple objects can be hooked to the timer to be called when their interval elapses. The driver allows new timed_objects to be added as needed.
NOTE: Only one of the timer_driver objects is allowed per program.

| bool timer_driver::set_timer | ( | int | duration, | |
| timed_object * | to_invoke | |||
| ) |
sets a timer to call "to_invoke" every "duration" milliseconds.
if the object "to_invoke" already exists, then its duration is changed.

| bool timer_driver::zap_timer | ( | timed_object * | to_drop | ) |
removes the timer that was established for "to_drop".
do not zap a timer from its own callback! that could cause synchronization problems.
