Hi,
freopen closes stdout, but it seems that fclose doesn't restore it (see sample below).
How can one print to stdout after using freopen?

I have a C program that writes binary output to stdout,
which works fine in Unix/Linux. But when someone else
compiled and ran it in Windows, every time the program
emitted a 0x0A, Windows interpreted it as an lf, and
preceded it with a spurious 0x0D cr. Cute. Is there
some way I can freopen() (so to speak) stdout in binary
mode under Windows so that doesn't happen? Hopefully,
the fix would be portable, so it could compile and...

Hi,
I am a bit confused about the behaviour of freopen() and the standard
i/o streams.
I am trying to redirect a stream (stderr) to a particular "file". But,
if the call fails I want it to stay as it was, or at least be able to
redirect it somewhere else (e.g. stdout).
For example I would like to do,

I have checked: http://c-faq.com/stdio/undofreopen.html and don't
believe it addresses my question. I am dealing with large files of
numbers and want to take in small chunks and act on them--sometimes
using information based on the whole file. My approach is to read in
the whole file in chunks, place it in tempfile = tmpfile(); and then
run this back through. However, sometimes I will bypass this option
and read the chunks outright (not...

Hi All,
I have a question regarding the standard C library.
Is it possible to have one process (program) that
redirects its stdin to a file, and have a second program
use that file write/append to that file. The first program
will then read its redirected standard input file and
process that...

Hello all,
a while ago I was pointed towards freopen as a way to redirect stderr to a
log file. It works great, but apparently the app also writes a few lines to
stdout. Now I could redirect to 2 separate files, but would rather keep the
2 flows together.
Is it correct to do this:
stderr=freopen(LogFile, "w", stderr);
stdout=freopen(LogFile, "a", stdout);

Hello,
I have written a program in C; this programs uses an external
proprietary library. When calling a certain function in the external
library, the particular function writes a message to stdout. I am not
particularly interested in this message, and would like to silence it
- however I do not know how to do it. (I stdout and stderr my self, so
just redirecting into oblivion is not an option).
An excerpt of the code looks like this:

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
