It doesn't work. It's undefined behaviour. On NetBSD, it will fail with EBADF, if fd 0 isn't open for write, or if fd 0 is open for write, it will write heap garbage to fd 0. If stream points to an output stream or an update stream in which the most recent operation was not input, the fflush function causes any unwritten data for that stream to be delivered to the host environment to be written to the file; otherwise, the behavior is undefined. (ISO C11 and ISO C17, Sec. 7.21.5.2 `The fflush function') PR lib/58206 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114879 |

NetBSD
NetBSD is a free, fast, secure, and highly portable Unix-like Open Source operating system. It is available for a wide range of platforms, from large-scale servers and powerful desktop systems to handheld and embedded devices.
Building
You can cross-build NetBSD from most UNIX-like operating systems. To build for amd64 (x86_64), in the src directory:
./build.sh -U -u -j4 -m amd64 -O ~/obj release
Additional build information available in the BUILDING file.
Binaries
Testing
On a running NetBSD system:
cd /usr/tests; atf-run | atf-report
Troubleshooting
- Send bugs and patches via web form.
- Subscribe to the mailing lists. The netbsd-users list is a good choice for many problems; watch current-users if you follow the bleeding edge of NetBSD-current.
- Join the community IRC channel #netbsd @ libera.chat.
