Public domain editing routines

[Don Thomson]

In the spirit of not reinventing the wheel, I'm looking for public domain C
source on which to base a set of generic editing routines for entering fields
of data of different types: string, multiple-row text, integer, float, choice
of scalar values (i.e. Yes/No), etc.  The routines would need to be as
portable as possible and would presumably be curses based.  The string/text
fields would allow modification of existing text and choice of insert/overtype
modes.  The numeric and scalar fields would check for entry of legal values
(i.e. digits and decimal point) with each key stroke (as opposed to verifying
legality after pressing <RETURN>).  Any recommendations for code that
implements these kind of routines well and is available via anonymous ftp?
Thanks.
