Functions
dup(fd)—Creates a new OwnedFd instance that shares the same
underlying file description as fd.
dup3(fd, new, flags)—Creates a new OwnedFd instance that shares the
same underlying file description as the existing OwnedFd instance,
closing new and reusing its file descriptor.
ioctl(fd, FIOCLEX)
ioctl(fd, FIONREAD).
ioctl(fd, TCGETS)
ioctl(fd, TIOCGWINSZ).
Returns a pair of booleans indicating whether the file descriptor is readable and/or writeable, respectively.
