If you are only worried about buffer overflow attacks, but would
otherwise like a string, you can use fgets. If you want a single
character, but would allow the user normal input editing, you can use
getc/getchar/fgetc. If you really want to do low-level terminal IO, you
will probably need one or more of the termios functions. (man termios,
or info libc low level terminal interface).
Oh, if it's a gui shell(?), there's vga_getkey().
