Function rustix::io::close

source · []
pub unsafe fn close(raw_fd: RawFd)
Expand description

close(raw_fd)—Closes a RawFd directly.

Most users won’t need to use this, as OwnedFd automatically closes its file descriptor on Drop.

This function does not return a Result, as it is the responsibility of filesystem designers to not return errors from close. Users who chose to use NFS or similar filesystems should take care to monitor for problems externally.

Safety

This function takes a RawFd, which must be valid before the call, and is not valid after the call.
