This header was originally in the C standard library as <signal.h>.

This header is part of the program support library.

Typedefs
sig_atomic_t	the integer type that can be accessed as an atomic entity from an asynchronous signal handler (typedef)
Macros
SIGABRTSIGFPESIGILLSIGINTSIGSEGVSIGTERM	defines signal types (macro constant)
SIG_DFLSIG_IGN	defines signal handling strategies (macro constant)
SIG_ERR	return value of signal specifying that an error was encountered (macro constant)
Functions
signal	sets a signal handler for particular signal (function)
raise	runs the signal handler for particular signal (function)

Synopsis

namespace std {
  using sig_atomic_t = /* implementation-defined */;
  void (*signal(int sig, void (*func)(int)))(int);
  int raise(int sig);
}
