Note that the chat logging SPI is documented in thetoolkit file stddatkdevguide.pdf:►►stDdaClInit: Called one time when the server loads the chat logging DLL. Thisis where you do all of your one-time setup, such as initializing the Notes API.stDdaClTerminate: Called one time when the Sametime server is about toshut down. Anything that you allocated or initialized in the Init call would bedeallocated or terminated in this call.Chapter 5. Chat Logging/DDA Toolkit 135
