<H1><A NAME="_tapi2_lineproxymessage"></A>lineProxyMessage</H1>
<P>The <B>lineProxyMessage</B> function is used by a registered proxy request handler to generate TAPI messages related to its role. For example, an ACD agent handler can use this function to generate <A HREF="msgs_0mr7.htm" tppabs="http://msdn.microsoft.com/library/psdk/tapi22/msgs_0mr7.htm">LINE_AGENTSTATUS</A> messages that are received by all applications that have the specified line open. TAPI suppresses generation of the message on the <I>hLine</I> specified in the function parameters. </P>

<H4>Parameters</H4>
<DL>
<DT><I>hLine</I> </DT>
<DD>A handle to the open line device. This is converted by TAPI into the correct <I>hLine</I> for each application that receives the message. </DD>

<DD>If the message is related to a specific call (which it is not, in the case of LINE_AGENTSTATUS), specifies the proxy handler's handle to that call; shall be set to NULL for messages not related to a specific call. This is converted by TAPI into the correct <I>hCall</I> for each application that receives the message. </DD>
<DT><I>dwMsg</I> </DT>
<DD>The TAPI message to generate. This must be a message that is permitted to be generated by proxy handlers. </DD>
<DT><I>dwParam1</I> </DT>
<DT><I>dwParam2</I> </DT>
<DT><I>dwParam3</I> </DT>
<DD>The parameters associated with the message to be sent.
