Routine Description:

    FmtNcbName - format a name NCB-style
 
    Given a name, a name type, and a destination address, this
    function copies the name and the type to the destination in
    the format used in the name fields of a Network Control
    Block.
 

    SIDE EFFECTS
 
    Modifies 16 bytes starting at the destination address.

Arguments:

    DestBuf - Pointer to the destination buffer.

    Name - Unicode NUL-terminated name string

    Type - Name type number (0, 3, 5, or 32) (3=NON_FWD, 5=FWD)



Return Value:

    NERR_Success - The operation was successful

    Translated Return Code from the Rtl Translate routine.
