PAPI_accum(3) PAPI PAPI_accum(3)NAMEPAPI_accum-
Accumulate and reset counters in an EventSet.
SYNOPSISDetailed Description
@par C Interface:
int PAPI_accum( int EventSet, long_long * values );
These calls assume an initialized PAPI library and a properly added event set.
PAPI_accum adds the counters of the indicated event set into the array values.
The counters are zeroed and continue counting after the operation.
Note the differences between PAPI_read and PAPI_accum, specifically
that PAPI_accum resets the values array to zero.
@param EventSet
an integer handle for a PAPI Event Set
as created by PAPI_create_eventset
@param *values
an array to hold the counter values of the counting events
@retval PAPI_EINVAL
One or more of the arguments is invalid.
@retval PAPI_ESYS
A system or C library call failed inside PAPI, see the errno variable.
@retval PAPI_ENOEVST
The event set specified does not exist.
@par Examples:
* do_100events( );
* if ( PAPI_read( EventSet, values) != PAPI_OK )
* handle_error( 1 );
* // values[0] now equals 100
* do_100events( );
* if (PAPI_accum( EventSet, values ) != PAPI_OK )
* handle_error( 1 );
* // values[0] now equals 200
* values[0] = -100;
* do_100events( );
* if (PAPI_accum( EventSet, values ) != PAPI_OK )
* handle_error( 1 );
* // values[0] now equals 0
