Function Documentation

statistics_counter_event()

void statistics_counter_event ( struct function * fn, const char * id, int incr )

extern

Add statistics information about event ID in function FN.
This will increment the counter associated with ID by INCR.
It will also dump the event to the global statistics file if requested.

statistics_histogram_event()

void statistics_histogram_event ( struct function * fn, const char * id, int val )

extern

Add statistics information about event ID in function FN with the
histogram value VAL.
