PAPI_query_event man page

PAPI_query_event — Query if PAPI event exists.

Detailed Description

C Interface:

#include <papi.h>
int PAPI_query_event(int EventCode);

PAPI_query_event() asks the PAPI library if the PAPI Preset event can be counted on this architecture. If the event CAN be counted, the function returns PAPI_OK. If the event CANNOT be counted, the function returns an error code. This function also can be used to check the syntax of native and user events.

Parameters:

EventCode -- a defined event such as PAPI_TOT_INS.

Return values:

PAPI_EINVAL One or more of the arguments is invalid.
PAPI_ENOEVNT The PAPI preset is not available on the underlying hardware.

Examples

int retval;
// Initialize the library
retval = PAPI_library_init(PAPI_VER_CURRENT);
if (retval != PAPI_VER_CURRENT) {
  fprintf(stderr,
  exit(1); 
}
if (PAPI_query_event(PAPI_TOT_INS) != PAPI_OK) {
  fprintf(stderr,
  exit(1);
}
