InitCTree and InitCTreeXtd
This function must be called before using any FairCom DB functions, unless you are using ISAM functions, which require a different initialization function. It initializes the FairCom DB buffers for the number of files that you are going to use. If you are using the FairCom Server, it also logs you on to the Server.
If you are using the FairCom Server, and you are not using the ISAM functions, you must call StopUser() when you are finished using the Server, typically just before you exit the application. If you are not using a Server, this function is ignored.
