LEGACY STORAGE FORMAT

        The format has been chosen so that it will be the same on all hardware.

+       names with members of a TERMTYPE structure.
+

EXTENDED NUMBER FORMAT

+       On occasion, 16-bit signed integers are not large enough.  With ncurses
+       6.1,  a  new format is introduced by making a few changes to the legacy
+       format:
+
+       o   a different magic number (0542)
+
+       o   changing the type for the number array from signed 16-bit  integers
+           to signed 32-bit integers.
+
+       To  maintain  compatibility,  the library presents the same data struc-
+       tures to direct users of the TERMTYPE structure as in previous formats.
+       However,  that  cannot  provide callers with the extended numbers.  The
+       library uses a similar but hidden data structure TERMTYPE2  to  provide
+       data for the terminfo functions.

+       ties.
+
+       A small number of terminal descriptions  use  uppercase  characters  in
+       their  names.   If  the  underlying  filesystem  ignores the difference
+       between uppercase and lowercase, ncurses represents the "first  charac-
+       ter" of the terminal name used as the intermediate level of a directory
+       tree in (two-character) hexadecimal form.
