Function rustix::io::take_stdout
source · pub unsafe fn take_stdout() -> OwnedFdExpand description
STDOUT_FILENO—Standard output, owned.
This is similar to stdout, however it returns an OwnedFd which closes
standard output when it is dropped.
Safety
This is unsafe for the same reasons as stdout.
Other hazards
This has the same hazards as stdout.
And, when the OwnedFd is dropped, subsequent newly created file
descriptors may unknowingly reuse the stdout file descriptor number, which
may break common assumptions, so it should typically only be dropped at the
end of a program when no more file descriptors will be created.
