That will be a real breakthrough for interbase/firebird protocols - as far as I know there never used to be such docs. > > For a non-C++ programmer the Firebird code can be a real maze when > looking for where things are defined and how they are defined and how > things go together (as an example: ClntAuthBlock is implemented > partially in remote.cpp and interface.cpp); I know it's a bad way - but it was a simplest one to avoid unresolved externals in both client & server at the same time avoiding inclusion of too many unneeded code at both sides. > I need to keep switching > between remote.cpp, interface.cpp, and inet.cpp Feel lucky that you do not deal with windows - there are also xnet & wnet in it ;) ------------------------------------------------------------------------------ Monitor Your Dynamic Infrastructure at Any Scale With Datadog!
