Checks whether a terminal is attached to another node by a connector. It returns an integer value that specifies whether the specified terminal object is attached to one or more terminals on other message flow nodes. You can use it to test whether a message can be propagated to a terminal. However, it is not necessary to call this function before propagating a message with the cniPropagate utility function. Using the cniIsTerminalAttached function, a node can modify its behavior when a terminal is not connected.
if (terminalObject) { if (cniIsTerminalAttached(&rc, terminalObject)) { if (rc == CCI_SUCCESS) { retvalue = cniPropagate( &rc, terminalObject, destinationList, exceptionList, message);
