       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.

	   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.


	   * 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);
	   * }
