SIGNAL-SAFETY(7) Linux Programmer's Manual SIGNAL-SAFETY(7) NAME top signal-safety - async-signal-safe functions DESCRIPTION top An async-signal-safe function is one that can be safely called from within a signal handler. Many functions are not async- signal-safe. In particular, nonreentrant functions are generally unsafe to call from a signal handler.

Die meisten Signale bewirken auch eine Aktion – meist das Beenden des Prozesses. SIGEMT is not specified in POSIX.1-2001, but nevertheless appears on most other UNIX systems, where its default action is typically to ter‐ minate the process with a core dump. SIGPWR (which is not specified in POSIX.1-2001) is typically ignored by default on those other UNIX systems where it appears. the (modern) "POSIX" function used to mask signals in the global context, is the sigprocmask () system call. It allows us to specify a set of signals to block, and returns the list of signals that were previously blocked. Se hela listan på tutorialspoint.com The behaviour of ‘signal’ is different in different platforms.
See Signal Actions for the complete list of functions you can call from Unix signal handlers. But don't despair, there is a way to use Unix signal handlers with Qt. The strategy is to have your Unix signal handler do something that will eventually cause a Qt signal to be emitted, and then you simply return from your Unix signal handler.
