/*
* Synopsis
* bool yes_or_no(bool read_only);
*
* Arguments
* read_only
* In read-only mode, all questions are answered "no". It
* will print "No" to stdout.
*
* Description
* After a yes/no question, this function gets the answer from the
* user.
*
* Calls to this function will normally be preceeded by a prompt on
* stdout, so we should fflush(3).
*
* Return value
* false "no"
* true "yes"
*
* See also
* rpmatch(3)
