  • 1.  function pointer is not initializing to NULL

    Hi,

    I'm using AIX 5.1 and gcc 4.0 version to build my software. Here I'm finding some problem in runtime.
    Here we have static function pointer that is initialized to NULL. Here is the below cases...

    static int (*retrivalFunc)(char *attr, char *option, returnCode *codePtr, char *buf) = NULL;

    sampleFunc() {

    if (attRetrivalfunc != NULL) {
    return(retrivalFunc(attName, dataBuf,codePtr, msg));
    }
    }

    Here at run time for the first only directly its coming to this if loop (ie. !=NULL case), and causing problem.
    But if I remove the NULL initialization, its working fine. I think 'static' will initialize. But why this is not initializing if I explicitly do? Is this problem with AIX environment or gcc? Thanks for any suggestion!
    Thanks & Regards,
    Sharath.

    same result when you compile without optimization?

    yeah, without -O option also is not working. If i will not initialize this static variable to NULL, then its working on AIX.I think static will automatically initialize to NULL, but explicit initialization to NULL is not working in AIX.
    But this code is working fine in linux.
