Thus a windows implementation of this file which only implements the wrapped curses functions -- by wrapping windows drawing calls is fine. More...

Detailed Description

This is really a .c file, not a .h file. It defines a wrapper around curses that is used by cursorwindow.c. This wrapper is what is needed not the raw curses calls. Thus a windows implementation of this file which only implements the wrapped curses functions -- by wrapping windows drawing calls is fine.

Note that this file defines its own keyboard reading routine because the getch() function provided by curses doesn't consistently work across all situations where you do something like the following:

   rlogin machine1
   rlogin machine2
   rlogin machine3
   run a curses program
   and press a function key

In the above scenario, it is likely that your function key will be lost -- that is broken up into the individual characters that comprise the sequence.

The 'read_mapped_key' function solves this problem by exotic ioctl and termios magic.

Note that a user's XTerm resources can screw up function key bindings and there is nothing you can do to fix the problem automatically. We can only hope that the isn't doing such things....
