[Winpcap-users] Entry Point in a DLL

Hello Thomas,

I think I'm trying to do something similar but with a standard library I
(think) am statically linking.  I'm getting link errors about unresolved
externals.  I am try to build the wpa_cli into a class.

I think my problem is about a class (cpp) file not understanding a lib build
from straight "C" and thereby not finding a c style functions.

Either I'm getting forgetful (very possible), or involved with .net too much
too recently to remember (also possible) that I'm forgeting the way to link
C-style functions into a cpp module and call those external functions.

What am I forgetting?? Or am I forgetting that it is impossible.  I thought
I needed to declare the externals with something like __decl or with "C"
inside the cpp file???????

thanks for any of your ideas,
