"If fildes refers to the master side of a pseudo-terminal, and this
is the last close, a SIGHUP signal shall be sent to the controlling
process, if any, for which the slave side of the pseudo-terminal is
the controlling terminal. It is unspecified whether closing the
master side of the pseudo-terminal flushes all queued input and
output."
I don't find such implementation on cygwin
fhandler_pty_master::close ()
Am I looking in the wrong place ?
No, I don't think so. I'm not fluent with mc. How can I reproduce
the issue?
