Using C libraries

[Laughlin, Joseph V]

Has anyone had any difficulties using C libraries / data structures with
python? Are there any things I need to be aware of?

Re: Using C libraries

Depends on what you mean by "difficulti es". I've interfaced
Python with lots of different .DLL libraries. The "tricky"
part is getting enough information about the proper data
structures for calling the external functions. Much study
of struct module is normally required. And you need either
my DLLInterface code:

or you can use Thomas Heller's ctypes module:

Or you can roll your own...
