PAPI_stop(3) PAPI PAPI_stop(3)NAMEPAPI_stop-
Stop counting hardware events in an event set.
SYNOPSISDetailed Description
C Interface:
#include <papi.h>
int PAPI_stop( int EventSet, long long * values );
Parameters:
EventSet -- an integer handle for a PAPI event set as created by
PAPI_create_eventset
values -- an array to hold the counter values of the counting
events
Return values:
PAPI_OK
PAPI_EINVAL One or more of the arguments is invalid.
PAPI_ESYS A system or C library call failed inside PAPI, see the
errno variable.
PAPI_ENOEVST The EventSet specified does not exist.
PAPI_ENOTRUN The EventSet is currently not running.
PAPI_stop halts the counting of a previously defined event set and the
counter values contained in that EventSet are copied into the values
array Assumes an initialized PAPI library and a properly added event
set.
Example:
int EventSet = PAPI_NULL;
long long values[2];
int ret;
ret = PAPI_create_eventset(&EventSet);
if (ret != PAPI_OK) handle_error(ret);
// Add Total Instructions Executed to our EventSet
ret = PAPI_add_event(EventSet, PAPI_TOT_INS);
if (ret != PAPI_OK) handle_error(ret);
// Start counting
ret = PAPI_start(EventSet);
if (ret != PAPI_OK) handle_error(ret);
poorly_tuned_function();
ret = PAPI_stop(EventSet, values);
if (ret != PAPI_OK) handle_error(ret);
printf('%lld\n',values[0]);
