Routine Description:

    Writes an error message and ascii string to the error log.  Also,
    writes the data in the data buf if there are any.

Arguments:

    MessageId           - Message ID

    InsertionString     - at most one asciiz string (may be NULL)

    RawDataBufferLength - size of data to be printed from the auxiliary data
            buffer.  May be zero, in which case the actual value depends on
            "RawDataBuffer".  It is 0 if "RawDataBuffer" is NULL, else it is
            "sizeof( wchar) * wcslen( RawDataBuffer)".

    RawDataBuffer       - data buffer containing secondary error code & some
            other useful info.  Must be NULL terminated string or NULL if
            "RawDataBufferLength" is zero.

Return Value:

    None.
