accessing dll functions

[mxb7642]

I'm trying to access a dll through python using ctypes. So far, i can successfully load standard windows dll's such as kernel32 and msvcrt. I can also access methods that they contain. However, when i try to reproduce this with a custom dll, i can only load, but not access the methods. Could this be a permissions issue? I've also seen something about "public interfaces" - would that be of any use?
Any help will be greatly appreciated. Thank you.

Use the module dl instead of ctypes. That is a standard python module for dynamically loading libraries cross-platform.
