Gdb works on any program its not special to python. Victor is only talking about a specific use of gdb for python c extensions.

Re: Debugging Python C extensions with GDB
Thanks for your reply. Victor's article didn't mention ctypes extensions, so I wanted to post a question before I build from source.

Yes. Just put a breakpoint on the function in the c library that you want to debug. You can set the breakpoint before a .so is loaded.

Debugging Python C extensions with GDB
In September 2021, Victor Stinner wrote “Debugging Python C extensions with GDB” (https://developers.redhat.com/articles/2021/09/08/debugging-python-c-extensions-gdb#getting_started_with_python_3_9). My question is: with Python 3.9+, can I debug into a C extension written in pure C and called from ctypes -- that is not written using the C_API? Thanks.
