11.9 Extended interface to GNU Readline

The library (vicare readline) extends the basic readline API exported by (vicare) (see iklib readline) with features specific to the GNU Readline library. The following bindings:

     readline-enabled?
     readline
     make-readline-input-port

exported by (vicare) are reexported by (vicare readline).

— Function: rl-version

If support for readline is enabled and the linked library is GNU Readline: return an exact integer representing the GNU Readline version number as encoded in the C symbol RL_READLINE_VERSION; else return #f. When this function returns #f: no other GNU Readline functions must be called, lest the process be aborted.
