I haven't actually tested that type of code, but there are going to be some
runtime penalties for running through all those select statements. Will they
really be select statements? I didn't think that C++ allowed select on a
Also, I have no been successful invoking C/C++ functions from C# where the C
function takes a variable number of arguments. I don't think that P/Invoke
really supports that. Gopal said that Pnet supports it, but that is not
portable. I'm pretty sure that Mono and .NET will have problems with it.
I don't mean to sound discouraging. Overcoming the name mangling problems is a
big hassle. In the new version of Qt#, we're extracting the mangling names
from the shared library at build time, in case you're interested.
