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:

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

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_named_event('PAPI_TOT_INS') != PAPI_OK) {
fprintf(stderr,´No instruction counter? How lame.\n´);
exit(1);
}
