Query if papi event exists.
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); * } *
