int cidx, result;
cidx = PAPI_get_component_index("example");

PAPI_library_init();

PAPI_disable_component() allows the user to disable components before PAPI_library_init() time. This is useful if the user knows they do not wish to use events from that component and want to reduce the PAPI library overhead.
