* FUNCTION: HtalLibHeadpatch::HtalLibSendReply
*
* DESCRIPTION: Ohhh...I'm going to Programmer Hell for this one...
* We call DlkDispatchRequest to install the user name in
* our UIInitialize patch. DlkDispatchRequest will
* eventually call HtalLibSendReply to return a result
* code. Well, we haven't fired up the Htal library, and
* wouldn't want it to send a response even if we had.
* Therefore, I'll subvert the whole process by setting
* the HTAL library refNum passed in to the Desktop Link
* Manager to an invalid value. I'll look for this
* value in the SysTrap handling code and no-op the call
* by calling this stub.
*
* PARAMETERS: none
*
* RETURNED: nothing
*
