NAME

	CMD_WRITE -- Write to a clip on the clipboard.

FUNCTION

	This command writes data to the clipboard.  This data can be
provided sequentially by clearing io_Offset for the initial
write, and using the incremented value unaltered for
subsequent writes. If io_Offset is ever beyond the current
clip size, the clip is padded with zeros.
If this write is in response to a SatisfyMsg for a pending
post, then the io_ClipID returned by the CBD_POST command must
be used. Otherwise, a new ID is obtained by clearing the
io_ClipID for the first write. Subsequent writes must not
alter the io_ClipID.
IO REQUEST
io_Message mn_ReplyPort set up
io_Device preset by OpenDevice
io_Unit preset by OpenDevice
io_Command CMD_WRITE
io_Length number of bytes from io_Data to write
io_Data pointer to block of data to write
io_Offset usually zero if this is the initial write
io_ClipID zero if this is the initial write, ClipID of
the Post if this is to satisfy a post

RESULT

	io_Error	non-zero if an error occurred
io_Actual filled with the actual number of bytes written
io_Offset updated to next write position
io_ClipID the clip ID assigned to this write: do not
alter for subsequent writes
