Wow Salem, it's like you can see into the future. I shouldn't have writen off your comment so quickly. I now use the following for my main function template:

Code:

int main (int argc, char *argv[] __attribute__((unused)))
{
// Check number of arguments.
    if(argc != 1)
    {
        fprintf(stderr, "Usage: %s\n", argc ? program_invocation_short_name : "");
        exit(EXIT_FAILURE);
    }

// Run process.
    run_process();

// Exit cleanly.
    exit(EXIT_SUCCESS);
}

Ty.
