NAME

       PAPI_query_event - Query if PAPI event exists.

SYNOPSIS

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,\"PAPI library init error!\\n\");
             exit(1);
           }
           if (PAPI_query_event(PAPI_TOT_INS) != PAPI_OK) {
             fprintf(stderr,\"No instruction counter? How lame.\\n\");
             exit(1);
           }
