Why does loading the libc shared library have “'LibraryLoader' object is not callable” error?

Question

From https://en.wikipedia.org/wiki/Foreign_function_interface

the ctypes module can load C functions from shared libraries/DLLs on-the-fly and translate

Answer 1

You're confusing lower case cdll (which is a LibraryLoader) with upper case CDLL, which is the constructor for shared libraries.

This code will work as expected:

libc = ctypes.CDLL("/lib/x86_64-linux-gnu/libc.so.6")
