I know that there are many questions that are about "reading input" but to clarify I am trying to read cooked input. For some reason fgets is not cooked (Not sure if thats by default or I need to turn it on using termios) So any help? ncurses is not an option.

example: input hey then back space, it comes out as hey^H which is indicative of raw input mode

BTW I tried turning on canononical mode via termios and I'm still having trouble getting cooked input.

The shell isn't involved when a program is running. – Barmar Oct 22 '12 at 17:29
Mk then, it has to work regardless of the shell being used. – user1659134 Oct 22 '12 at 17:30
line by line retrieval of input from the user where the user is capable of editing (IE Delete backspace arrow keys) – user1659134 Oct 22 '12 at 17:39
does one need to trace all the keys pressed during program being executed? – जलजनक Oct 22 '12 at 17:40
Cooked mode is normally the default. However, the erase/kill characters may not be set as you expect, check that. – Barmar Oct 22 '12 at 17:42
@SparKot It's not needed but it wouldn't be hard to – user1659134 Oct 22 '12 at 17:44
@Barmar I'll check that out now. – user1659134 Oct 22 '12 at 17:44
check ioctl() as well to use raw mode. – जलजनक Oct 22 '12 at 17:50
termios is the struct used for wrappers with ioctl. And I wouldn't want to make it raw because that disables delimiters by newline, as well as processing. – user1659134 Oct 22 '12 at 17:54
@Barmar The Special character values are all set to default – user1659134 Oct 22 '12 at 17:54
The default erase character may be DEL (ASCII 127), but your backspace key is sending BS (ASCII 8). – Barmar Oct 22 '12 at 18:02
That is true.And Delete does work but arrow key navigation does not work. Which I don't think can be achieved by this method. I'd have to use ncurses to acheive that right? – user1659134 Oct 22 '12 at 18:04
