Standard C Library Functions                     siginterrupt(3C)



NAME
     siginterrupt - allow signals to interrupt functions

SYNOPSIS
     #include 

     int siginterrupt(int sig, int flag);


DESCRIPTION
     The siginterrupt() function  changes  the  restart  behavior
     when  a function is interrupted by the specified signal. The
     function siginterrupt(sig, flag) has an effect as if  imple-
     mented as:

       siginterrupt(int sig, int flag) {
            int ret;
            struct sigaction act;
            (void) sigaction(sig, NULL, &act);
            if (flag)
                 act.sa_flags &=  SA_RESTART;
            else
                 act.sa_flags |= SA_RESTART;
            ret = sigaction(sig, &act, NULL);
            return ret;
       }


RETURN VALUES
     Upon successful completion, siginterrupt() returns 0. Other-
     wise, -1 is returned and errno is set to indicate the error.

ERRORS
     The siginterrupt() function will fail if:

     EINVAL    The sig argument is not a valid signal number.


USAGE
     The siginterrupt() function  supports  programs  written  to
     historical system interfaces. A standard-conforming applica-
     tion, when being written or  rewritten,  should  use  sigac-
     tion(2) with the SA_RESTART flag instead of siginterrupt().
