Shouldn't you be sending the SIGHUP to the shell's process group instead
of just to shell? E.g.
} else if(e->xclient.data.l[0] == xw.wmdeletewin) {
/* Send SIGHUP to shell */
- kill(pid, SIGHUP);
+ kill(-pid, SIGHUP);
exit(EXIT_SUCCESS);
}
xterm does this[1]. SIGWINCH should be sent the same way but I'm not
sure how is st handling that (I'm not using it, I'm just a lurker).
