PAPI_is_initialized Class Reference

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.
