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

ERRORS

     [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.

     (``POSIX.1'') revision of the standard.
