101 dnl Searches for a readline compatible library. If found, defines
102 dnl `HAVE_LIBREADLINE'. If the found library has the `add_history'
103 dnl function, sets also `HAVE_READLINE_HISTORY'. Also checks for the
104 dnl locations of the necessary include files and sets `HAVE_READLINE_H'
105 dnl or `HAVE_READLINE_READLINE_H' and `HAVE_READLINE_HISTORY_H' or
106 dnl 'HAVE_HISTORY_H' if the corresponding include files exists.
108 dnl The libraries that may be readline compatible are `libedit',
109 dnl `libeditline' and `libreadline'. Sometimes we need to link a termcap
110 dnl library for readline to work, this macro tests these cases too by
111 dnl trying to link with `libtermcap', `libcurses' or `libncurses' before
114 dnl Here is an example of how to use the information provided by this
115 dnl macro to perform the necessary includes or declarations in a C file:
117 dnl #include <config.h>
