[ctypes-users] Regarding external binding of functions

[muhammad w. s. <was...@gm...>]

Hi,

I am new to ctypes and I have a questions regarding external binding
of function using ctypes. The question is as follows,

Q. I have a simple library that uses function pointer of
hello_printf(const char *format, ...) in one of its API. While using
this library in C, I point the function pointer of hello_printf to
printf and code works seamlessly.
hello_printf is not the API but is used in the implementation of one
of the API's. The reason for this is that I want external application
using the library to provide implementation of printf to provide
flexibility and is common practice in C/C++.

I want to know that how I can achieve this external binding of
function pointer using ctypes i.e. point hello_printf() to printf in
python so on calling the API, it gets the right printf implementation.

I am not sure if I explained it well and I can post the code if there
is ambiguity in question.

Help would be highly appreciated and thanks in advance.
