Qt signals/slots have nothing to to with C/unix signals. The former is a system
for dispatching function calls. The latter is a system for handling asynchronous
hardware interrupts (it can also handle software signals sent with kill/raise).
Qt makes little use of C/unix signals - the only bit that I'm aware of is in
QProcess (SIGCHLD, SIGIO, SIGKILL, SIGTERM and SIGPIPE).
