NAME
PAPI_read_counters -
Read and reset counters.
SYNOPSIS
Detailed Description
@par C Interface:
int PAPI_read_counters( long long *values, int array_len );
Parameters:
*values an array to hold the counter values of the counting events
arry_len the number of items in the *events array
Precondition:
These calls assume an initialized PAPI library and a properly added event set.
Postcondition:
The counters are reset and left running after the call.
Return values:
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_read_counters() copies the event counters into the array *values.
do_100events();
if ( PAPI_read_counters( values, num_hwcntrs ) != PAPI_OK )
handlw_error(1);
// values[0] now equals 100
do_100events();
if ( PAPI_accum_counters( values, num_hwcntrs ) != PAPI_OK )
handle_error(1);
// values[0] now equals 200
values[0] = -100;
do_100events();
if ( PAPI_accum_counters(values, num_hwcntrs ) != PAPI_OK )
handle_error();
// values[0] now equals 0
