I've recently starting looking at and attempting to work with the
ncurses libs on linux. I currently have a loop that uses wgetch to read
chars from the user. I'm also using cbreak mode so the buffering is
turned off. I'm wondering if there's an easy way to detect when the
user hits delete or backspace. I'm also wondering if I'll need to learn
the terminfo libs to do this. Any ideas?

after getting a char via wgetch, i can compare it to KEY_BACKSPACE. This
only seams to work when TERM is set to linux and xterm, after having called
meta(<win *>, TRUE). I've only tried a few of the TERM options, but I was
hoping there was a more general way of doing so.

curses should do this,

man inopts
man getch

-r
