pub fn openpt(flags: OpenptFlags) -> Result<OwnedFd>Available on crate feature
pty only.Expand description
posix_openpt(flags)—Open a pseudoterminal device.
On Linux, an additional CLOEXEC flag value may be passed to request the
close-on-exec flag be set.
On Linux, if the system has no free pseudoterminals available, the
underlying system call fails with io::Errno::NOSPC, however this rustix
function translates that to io::Errno::AGAIN, so that the linux_raw and
libc backends have the same behavior.
