PAPI_stop(3) PAPI PAPI_stop(3)
NAME
PAPI_stop -
Stop counting hardware events in an event set.
SYNOPSIS
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_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
",values[0]);
*
