Function Documentation

static stats_counter_table_type curr_statistics_hash ( )

static

Return the current hashtable to be used for recording or printing
   statistics.

static statistics_counter_t* lookup_or_add_counter ( stats_counter_table_type  hash, const char *  id, int  val, bool  histogram_p  )

static

Lookup or add a statistics counter in the hashtable HASH with ID, VAL
   and HISTOGRAM_P.

void statistics_counter_event

(

)

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.
