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. NetBSD 8.0 April 30, 2010 NetBSD 8.0
