+ * 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
