ssiiggiiggnnoorree() is  a member of  the ssiiggsseett() family  of signal-handling system
calls.  It is equivalent to the system call

    sigset(sigtype, SIG_IGN);

This, in effect, tells the system to ignore all signals of type ssiiggttyyppee.

See the Lexicon entry for ssiiggnnaall()  for a list of recognized signals.  Note
that signal SSIIGGKKIILLLL cannot be ignored.

ssiiggiiggnnoorree() returns  zero if  all went well.   If something went  wrong, it
returns -1 and sets eerrrrnnoo to an appropriate value.
