backspace key code problem

[stefan]

Hello there, 

In my program I have a save dialog where I require
the user to enter a filename.

I used wgetnstr() to read the user's input, but when entering
the filename, one cannot use the backspace key to delete characters
to correct typos. Hitting backspace only results in a question mark in the
filename.

I browsed the source of wgetnstr() and it _does_ check for
KEY_BACKSPACE and calls a function to clear the last character in case
it was pressed.

getch() returns 8 for my backspace key, but KEY_BACKSPACE is defined as 263.

The left arrow key does a proper job of clearing the last character.
KEY_LEFT is defined as 260, getch() says my left arrow key is 27.

I am using the standard US keyboard layout and Ncurses 5.0, the one
that comes with Debian Woody.

Any ideas?

thanks
stefan
