Function nix::pty::ptsname_r [−][src]
pub fn ptsname_r(fd: &PtyMaster) -> Result<String>
Get the name of the slave pseudoterminal (see
ptsname(3)
)
ptsname_r()
returns the name of the slave pseudoterminal device corresponding to the master
referred to by fd
. This is the threadsafe version of ptsname()
, but it is not part of the
POSIX standard and is instead a Linux-specific extension.
This value is useful for opening the slave ptty once the master has already been opened with
posix_openpt()
.
