Function rustix::io::take_stdout

source · [−]
pub unsafe fn take_stdout() -> OwnedFd
Expand 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.
