This procedure starts a timer, measuring the elapsed time since the call.
|
||
|
|
Each call to this procedure should be matched by a call to
|
||
|
|
pika_debug_timer_end(), which returns the elapsed time.
|
||
|
|
|
||
|
|
If there is already an active timer, it is not affected by the call, however, a
|
||
|
|
matching pika_debug_timer_end() call is still required.

This procedure stops the timer started by a previous pika_debug_timer_start()
|
||
|
|
call, and prints and returns the elapsed time.
|
||
|
|
|
||
|
|
If there was already an active timer at the time of corresponding call to
|
||
|
|
pika_debug_timer_start(), a dummy value is returned.
