 Procedure:     LibMain ID:1
 Purpose:       Dll entry point.Called when a dll is loaded or
                unloaded by a process, and when new threads are
                created or destroyed.
 Input:         hDllInst: Instance handle of the dll
                fdwReason: event: attach/detach
                lpvReserved: not used
 Output:        The return value is used only when the fdwReason is
                DLL_PROCESS_ATTACH. True means that the dll has
                sucesfully loaded, False means that the dll is unable
                to initialize and should be unloaded immediately.
 Errors:
