Requires a Message Loop

Under Windows, if the application is a GUI application, then a Windows message loop already exists, and there is no need to create a message loop. If the socket components are used in a console application or service application, it is important to create a message loop using the methods supplied by the LLP components. For more information, see Running the LLP Components in a Windows Service.

Under Unix and Linux applications, the event loop is proprietary to Chameleon. Internally, the components are invoking the POSIX ::select call, and so it is always necessary to make use of the methods supplied on the LLP components to run a message loop. For more information, see Running the LLP components in Linux/Unix.

	It is important to understand that the messages handled by the message loop are not HL7 messages - they are operating system messages like "data received", "connection closed", etc.
