On failure an explanation will be printed to stderr, obtained from the explain_nice(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_nice_on_error function is used to call the nice(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_nice(3) function, but still returns to the caller. inc The inc, exactly as to be passed to the nice(2) system call.
