The function returns immediately and the SDK calls the default callback function, registered during the <B>UpnpRegisterClient</B> call, for each matching root device, device, or service. The application specifies the search type by the <B>Target</B> parameter. <P>Note that there is no way for the SDK to distinguish which client instance issued a particular search. Therefore, the client can get search callbacks that do not match the original criteria of the search. Also, the application will receive multiple callbacks for each search. <P></BLOCKQUOTE> <DL><DT><DT><B>Parameters:</B><DD><B>Hnd</B> - The handle of the client performing the search. <BR><B>Mx</B> - The time, in seconds, to wait for responses.
