Hi everybody, let me explain by problem: I am working on an application which consists in a C++ dll (numeric computations) and a Python IHM (Python/Tk), which must run under Linux and win32. My problem is the C++ lib does write stuffs on its stdout, and I would like to print those messages in a Tk frame. When I run the computation, it has it's own thread.
So my question is : how van I redirect the dll's stdout to something I can retrieve in Python (pipe, socket,...)? I can do it easily under Linux. I made tests with a socket which just works fine. In the threaded function (that will do the heavy computation), I write: import os, sys from socket import * s=socket(AF_UNIX, SOCK_STREAM) s.connect(...) os.dup2(sys.__stdout__.fileno(), s.fileno()) very_intensive_function(many_parameters) s.close() That's OK under Linux, but does not work under win32 (even if I use an INET localhost socket), cause I cannot do the os.dup2 trick (Windows does not want to consider a socket as a file! What a shity system!). So my question is : is there a simple solution ? I have tested different solutions. I am trying hacks with pipes created with the win32api. But I have not yet managed this simple operation. Note that I have no access to the dll source code, so I cannot modify it so it uses a named pipe (for example) as message output pipe instead os stdout...
