SIGIGNORE(3)			   BSD Library Functions Manual 		     SIGIGNORE(3)

NAME
     sigignore -- manipulate signal dispositions

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <signal.h>

     int
     sigignore(int sig);

DESCRIPTION
     This interface is made obsolete by sigaction(2).

     The sigignore() function sets the disposition of the signal sig to SIG_IGN.

RETURN VALUES
     If successful, the sigignore() function returns 0.  Otherwise -1 is returned and errno is
     set to indicate the error.

ERRORS
     The sigignore() function will fail if:

     [EINVAL]		The argument sig is not a valid signal number; or an attempt is made to
			ignore a signal that cannot be ignored, such as SIGKILL or SIGSTOP.

SEE ALSO
     sigaction(2)

STANDARDS
     The sigignore() function conforms to IEEE Std 1003.1-2001 (``POSIX.1'').  It was however
     marked as obsolete in the IEEE Std 1003.1-2008 (``POSIX.1'') revision of the standard.
