how to export functions by name for ctype

[rych]

I'm on Windows with VS2005 testing ctypes on a very simple dll
I create a test.dll project which exports a function fntest(). I don't
touch anything in the autogenerated source and build it. I can load
the dll but can't access the function by its name fntest. Only by
ordinal number or calling getattr with "?fntest@@YAHXZ". How do I
export functions by name? It's probably rather a VS2005 question, but
I'm a bit disappointed ctypes doesn't work with a default export
convention.

I guess you've compiled your DLL with C++ and the above is a C++
mangled name.

Either compile it with C, or export the names in an extern "C" { }
block.

That fixed it, thank you.
