Routine Description:

    Retreive and format a message and print it out in the console window.
    If the message cannot be located then a message if printed indicating
    such.

Arguments:

    SystemMessage - specifies whether the message is to be located in
        this module, or whether it's a system message.

    MessageId - If SystemMessage is TRUE, then this supplies a system message id,
        such as a Win32 error code. If SystemMessage is FALSE, the this supplies
        the id for the message within this module's resources.

    Args - supplies pointer to varargs structure containing arguments to be
        inserted in the message text.

Return Value:

    None.

Routine Description:

    Print a message that an operation could not be carried out because
    an API failed. The operation failed message is printed first,
    followed by the Win32 error message.

Arguments:

    Win32Error - supplies the return code from the API that failed.

    MessageId - supplies the identifier for a message in this module's
        resources, that explains the operation that failed.

    Additional arguments supply values to be inserted in the operation failed
    message text.

Return Value:

    None.
