This function creates a message instance belonging to (dialogclassname, messageclassname). The message instance created is usually used as a parameter to the synchronous function MXSend

 
  MX mx;
  MXMessage* pmessage;

  char* Buf;

  BUFFERPARM Buffer;

  MXInit (&mx, MXSERVER, NULL, NULL, 0, NULL);

/* Establish Connection with a Server and send a TCP message*/

  TCPCom = MXOpenTCP (&mx, "194.204.200.8", 21, IPPROTO_TCP, NULL, NULL, TRUE);
  if (!TCPCom) return 0;

  pmessage =  MXCreateMessage (&mx, TCP_SYS, "Stream");

  Buffer.BufferType = 'T';
  Buffer.BufferSize = strlen ("This is a text message") + 1;
  Buffer.BufferContent = "This is a text message";

  MXSetValue (pmessage, "Stream", 1, &Buffer);

  if (MXSend (&mx, TCPCom, message) <  0) 

    printf ("Error sending buffer\n");

  MXFreeMessage (&mx, pmessage);
