bsd_signal(3c)

Standard C Library Functions                                    bsd_signal(3C)



NAME
       bsd_signal - simplified signal facilities

SYNOPSIS
       #include <signal.h>

       void (*bsd_signal(int sig, void (*func)(int)))(int);

DESCRIPTION
       The bsd_signal() function provides a partially compatible interface for
       programs written to historical system interfaces (see USAGE below).


       The function call bsd_signal(sig, func) has an effect as if implemented
       as:

         void (*bsd_signal(int sig, void (*func)(int)))(int)
         {
              struct sigaction act, oact;

              act.sa_handler = func;
              act.sa_flags = SA_RESTART;
              sigemptyset(&act.sa_mask);
              sigaddset(&act.sa_mask, sig);
              if (sigaction(sig, &act, &oact) == −1)
                   return(SIG_ERR);
              return(oact.sa_handler);
         }



       The handler function should be declared:

         void handler(int sig);



       where  sig is the signal number. The behavior is undefined if func is a
       function that takes more than one argument, or an argument of a differ‐
       ent type.

RETURN VALUES
       Upon  successful  completion,  bsd_signal() returns the previous action
       for sig. Otherwise, SIG_ERR is returned and errno is  set  to  indicate
       the error.

ERRORS
       Refer to sigaction(2).

USAGE
       This  function  is  a direct replacement for the BSD  signal() function
       for simple applications that are installing  a  single-argument  signal
       handler  function.  If a BSD signal handler function is being installed
       that expects more than one argument, the application has to be modified
       to use sigaction(2). The bsd_signal() function differs from signal() in
       that the SA_RESTART flag is set and the SA_RESETHAND will be clear when
       bsd_signal()  is  used.  The  state of these flags is not specified for
       signal().
