check for initialization More...

Detailed Description

Return values:

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

Parameters:

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.

Examples:

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

PAPI_is_initialized() returns the status of the PAPI library. The PAPI library can be in one of four states, as described under RETURN VALUES.

Bug:: If you don't call this before using any of the low level PAPI calls, your application could core dump.
