This is a very hard requirement :(.
A colleague of mine uses the "PJSIP" open source library in his
project done with Delphi. Here he created a DLL in C with Microsoft
Visual Studio and calls the "flattened" functions in this DLL with his
Pascal project. The C-DLL is statically linked to the PJSIP library
functions provided.
Now the PJSIP library creates lots of threads and preforms callbacks
to the DLL from same. The DLL forwards theses callbacks towards the
Pascal code.
All this seems to work fine.
It would be a major shame if using Lazarus would prevent this kind of
projects.
It's not meant as a requirement - it's meant as list of considerations
where you pick one or more of them to solve your problem. The "problem"
might be too OS specific that you can say it always works or it doesn't
work. It depends on the case. I'll make this more clearly. Also, I'll
add all missing aspects Maik and Sven mentioned.

Alexander
