I did a little bit of digging, and the only reason I can figure the
HUP doesn't work after a restart is that the restarted image has it
defaulted to SIG_IGN. Since the SIGHUP handled is set up using the
following macro, that would explain why HUP on a restarted ctwm
doesn't work:
#define newhandler(sig, action) \
if (signal (sig, SIG_IGN) != SIG_IGN) (void) signal (sig, action)
Now, if someone could explain to me why that macro is used at all, I'd
be quite grateful. Is there any reason at all not to set up a new
handler if the previous handler is SIG_IGN? That looks very error
prone to me...
Cheers,
Richard
