[python-win32] Communicating symbols between extension modules

[Mark English]

Sorry, I didn't realise the two libraries were both written by you. That
does simplify things.

If exporting functions from one (_Cm.pyd) and importing them in the
other (_Qt.pyd) is an option, then you can link one (_Qt.pyd) to the
other (_Cm.pyd), which in msdev is known as creating a dependency, and
then just call the _Cm.pyd code as though it were part of _Qt.pyd. In
that sense, this is nothing to do with python - it's the standard way of
exporting symbols from a dll and using them in another project (static
linking). Static linking has some code maintenance and speed advantages
over dynamic linking (dynamic linking is using LoadProcess,
GetProcAddress).

If you still need to call "LoadProcess()" and _Cm.pyd isn't in your path
anyway, you can find out the path of your current module (_Qt.pyd) by
calling "GetModuleHandle()" and then "GetModuleFileName()".

Hope that all helps.

Cheers,
mE
