The following gets a MathLink connection and uses it to send a message to the kernel:

    MLINK link = libData->getMathLink(libData);
    MLPutFunction( link, "EvaluatePacket", 1);
    MLPutFunction( link, "Message", 2);
    MLPutFunction( link, "MessageName", 2);
    MLPutSymbol( link, "MyFunction");
    MLPutString( link, "info");
    MLPutString( link, "Message called from within DLL function.");
    libData->processMathLink( link);
    pkt = MLNextPacket( link);
    if ( pkt == RETURNPKT) {
        MLNewPacket(link);
    }
