Ctypes fails to resolve 'stdout' from msvcrt

I am trying to redirect stdout from DLL. This question asked plenty of times, but I decided to go through this article: redirecting-all-kinds-of-stdout-in-python

The problem is that when I am running this line:

c_stdout = ctypes.c_void_p.in_dll(libc, 'stdout')

I get

ValueError: symbol 'stdout' not found

I am initializing libc unlike the method mentioned in the article since it does not work:

libc = ctypes.CDLL(None)

So I am doing

libc = ctypes.CDLL('msvcrt')

instead, but then again it does not resolve "stdout" which seems essential to the case. Thanks. Any help redirecting output from the dll will be also great.

Might be an *XY Problem*. Describe what you're trying to achieve, and what's not working. – CristiFati Sep 04 '19 at 14:20

`stdout` is a macro (#define) in the CRT headers, not a global variable. – Mark Tolonen Sep 04 '19 at 14:36
Mark Tolonen: some DLL suppose to include it. do you know which? otherwise i t wouldnt have worked... – user2117099 Sep 08 '19 at 12:26
