PAPI_query_event -

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);
* }
