Routine Description:

    This routine prints the program name, the given printf-style formatted
    string, and the string of the current errno, separated by a colon and a

    value.

Arguments:

    ExitCode - Supplies the value to pass to exit.

    Format - Supplies the printf style format string.

    ... - Supplies the remaining arguments to the string.

Return Value:
