PAPI_stop Class Reference

Stop counting hardware events in an event set. More...

Detailed 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_EINVALOne or more of the arguments is invalid.
PAPI_ESYSA system or C library call failed inside PAPI, see the errno variable.
PAPI_ENOEVSTThe EventSet specified does not exist.
PAPI_ENOTRUNThe 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);
* ret = PAPI_stop(EventSet, values);
* if (ret != PAPI_OK) handle_error(ret);
* printf("%lld\\n",values[0]);
