NAME¶
PAPI_read_ts - Read hardware counters with a timestamp.
SYNOPSIS¶
Detailed Description¶
C Interface:
#include <papi.h>
int PAPI_read_ts(int EventSet, long long *values, long long *cycles );
int PAPI_read_ts(int EventSet, long long *values, long long *cycles );
PAPI_read_ts() copies the counters of the indicated event set into the provided array. It also places a real-time cycle timestamp into the cycles array.
The counters continue counting after the read.
PAPI_read_ts() assumes an initialized PAPI library and a properly added event set.
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
*cycles -- an array to hold the timestamp values
*values -- an array to hold the counter values of the counting events
*cycles -- an array to hold the timestamp values
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_ENOEVST The event set specified does not exist.
PAPI_ESYS A system or C library call failed inside PAPI, see the errno variable.
