PAPI_is_initialized (3)

@retval PAPI_NOT_INITED
    Library has not been initialized
@retval PAPI_LOW_LEVEL_INITED
    Low level has called library init
@retval PAPI_HIGH_LEVEL_INITED
    High level has called library init
@retval PAPI_THREAD_LEVEL_INITED
    Threads have been inited

@param version
 upon initialization, PAPI checks the argument against the internal value of PAPI_VER_CURRENT when the library was compiled.
This guards against portability problems when updating the PAPI shared libraries on your system.
@par Examples:

        int retval;
        retval = PAPI_library_init(PAPI_VER_CURRENT);
        if (retval != PAPI_VER_CURRENT && retval > 0) {
        fprintf(stderr,"PAPI library version mismatch!\n");
        exit(1); }
        if (retval < 0)
        handle_error(retval);
        retval = PAPI_is_initialized();
        if (retval != PAPI_LOW_LEVEL_INITED)
        handle_error(retval);
