Library functions

[Tuvas]

I am writing a program that mimics a program written in C, but using
Python-supiorior techniques. The C program calles a library function,
non-open source, I only know that it sends it a command
LINUX_CAN_Open() as for a few others as well. Is there a way I can call
this function from Python without opening the code, as the library is
not open sourced (I know, a rarity with Linux libraries, but, well, it
appears not to be...)? Perhaps write a C function that acts as a
wrapper, is there a way to do it directly? Any help is much
appreciated! Thanks!

I've successfully used the ctypes module to call Windows DLLs
(coincidentally it's to send/receive CAN messanges). According
to the ctypes docs, you can use it to call functions in Linux
libraries as well.

How exactly do you do that? Just to get some kind of an idea, perhaps
you could share bits of code? Thanks!

Did you check out the ctypes web site before asking? See
http://starship.python.net/crew/theller/ctypes/ and at least read
through the helpful tutorial before asking questions which are almost
certainly covered there. For example, right there near the top of the
first screen in the tutorial is an example of opening a Linux .so file...
