C programming problem

[Bogdan Taru]

Hi everyone,

 I wanna make a shell (very simple - 4 commands only) and I want to
avoid the old programming problem of reading a string instead of a
character at a time (used for buffering overflow attacks). Could
somebody point to me such a C function which reads only one character at
a time, without buffering the whole line before? I tried using getch()
from ncurses library, but realized it's not very useful in my program...

Thanks & Have fun,
bogdan
