---------------------------------------------------------------------- (0003798) geoffclare (manager) - 2017-06-22 16:45 http://austingroupbugs.net/view.php?id=1151#c3798 ---------------------------------------------------------------------- I see a problem with this part of the tcsetsize() description:<blockquote>If the terminal is a slave pseudo-terminal, a SIGWINCH shall also be delivered to the foreground process group of the associated master pseudo-terminal. Similarly, if the terminal is a master pseudo-terminal, a SIGWINCH shall be delivered to the foreground process group of the associated slave pseudo-terminal.</blockquote> Currently the standard does not require the master side to provide a terminal interface nor require that it can have a controlling process or process groups. All it requires of the master is (XBD 3.308) "Anything written on the master device is presented to the slave as an input and anything written on the slave device is presented as an input on the master side." How best to solve this depends on whether existing applications expect the master side to be a terminal and for what reason (e.g. is it always just in order to receive SIGWINCH when the slave side changes size).
