Martin,

I'm quoting against the 2.1 code base. My code works against 2.2, but I'm sure these macros will break my code in mysterios ways in the future.

My app is embedding Python within it.

You can see my code in Python CXX connection on sourceforge.

Consider: my code attempts to load pythonXX.dll then if it is present I find all the procedures that I need. I cannot use MACROS with implicit references to functions, it will prevent me linking my app.

All the _Check macros cannot be used. I would like a C function.

The INCREF/DECREF family cannot be used and worse these change definition on various #ifdef's, which I have to supply matching implementations for to allow debug vs. release builds.

If you only use functions from the python DLL then delay loading can be used on windows. But there are all those unencapsulated variables that prevent this in a not trival app. They need a Get/Set interface.

    BArry

I need to be able to dynamically load python in my application. Python integration is optional. I can look use the GetProcAddress to get a real functions, but I have to know the implementation inside the macros and duplicate that code. If there are a pure procedural interface it would be a lot easier for my type of app.

Which macros would you like to avoid specifically?
