Specifying Signal Actions
=========================

   The simplest way to change the action for a signal is to use the
`signal' function.  You can specify a built-in action (such as to
ignore the signal), or you can "establish a handler".

   The GNU library also implements the more versatile `sigaction'
facility.  This section describes both facilities and gives suggestions
on which to use when.
