This is a working / running application, with context, no problem.

It looks like you are using ctypes, so I made few investigations and 
tried this :
I had the /usr/lib64/libgle.so library file in the system.
I made a symlink named "libGLE.so" in the same directory ===> now, 
PyOpenGL can run gle Commands !

That may give you some ideas...

without any context, the following gle command should work :
gleGetJoinStyle()
gleSetJoinStyle(...)
