signal(2) — manpages-dev — Debian buster — Debian Manpages See signal-safety(7) for a list of the async-signal-safe functions that can be safely called from inside a signal handler. The use of sighandler_t is a GNU extension, exposed if _GNU_SOURCE is defined; glibc also defines (the BSD-derived) sig_t if _BSD_SOURCE (glibc 2.19 and earlier) or _DEFAULT_SOURCE (glibc 2.19 and later) is defined. signal(3HEAD) (man pages section 3: Library Interfaces and The symbols SIGRTMIN through SIGRTMAX are evaluated dynamically in order to permit future configurability.. SIGNAL DISPOSITION. A process, using a signal(3C), sigset(3C) or sigaction(2) system call, may specify one of three dispositions for a signal: take the default action for the signal, ignore the signal, or catch the signal.. Default Action: SIG_DFL. A disposition of SIG_DFL specifies the
Mac OS X Manual Page For signal(3)
The only portable use of signal() is to set a signal's disposition to SIG_DFL or SIG_IGN.The semantics when using signal() to establish a signal handler vary across systems (and POSIX.1 explicitly permits this variation); do not use it for this purpose. POSIX.1 solved the portability mess by specifying sigaction(2), which provides explicit control of the semantics when a signal handler is signal(7) — manpages — Debian buster — Debian Manpages Sends a signal to a specified POSIX thread in the same process as the caller. tgkill(2) Sends a signal to a specified thread within a specific process. (This is the system call used to implement pthread_kill(3).) sigqueue(3) Sends a real-time signal with accompanying data to a specified process.
