From: Cyrill Gorcunov Date: Wed, 24 Oct 2012 19:43:21 +0000 (+0400) Subject: tty, ioctls -- Add new ioctl definitions for tty flags fetching X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c6298038bcfc20710430a4ad069bb1f3f069997c;p=openwrt%2Fstaging%2Fblogic.git tty, ioctls -- Add new ioctl definitions for tty flags fetching This patch defines new ioctl codes TIOCGPKT, TIOCGPTLCK, TIOCGEXCL for fetching pty's packet mode and locking state, and exclusive mode of tty. [ No real handlers for the codes though, this will be addressed in another patch for easier review and bisectability ] Signed-off-by: Cyrill Gorcunov CC: Alan Cox CC: "H.
