The module has been split into a generic part (routines logClient*), and a specific part (iocLog*). The latter ones now reside in a separate module named iocLog, but are still exported from logClient for backward compatibility. Routines logClientInit() and logClientSendMessage() are now deprecated (retained for backwards compatibility only) because they are not completely generic. Instead, the new routines logClientCreate() resp. logClientSend() should be used. Chapter 19.15, "logClient", of the Application Developer's Guide has been fleshed out to document how to use logClient as a general purpose IOC logging library.
