I want to have a simples function where I print on screen with printf() lots of text and then do not allow the user to type anything but the return key. When the user presses the return key, the function exits (automatically), but before that, I don't anything to be on screen if the user presses any keys...
How can I accomplish that?
Why would you want to do that?
If your compiler supports the non-standard function getch():
That might work. You may have to flush the input buffer with while(getchar()...) after using getch().Code:#include <conio.h> while(getch() != '\n');

nope, i'm using gcc, no conio available...
I think I could use curses/ncurses but I read that to run my app on another computer, that computer needs to have curses/ncurses library, my question is, isn't that only necessarya if compiling on another computer? Meaning, if I compile on my machine using those libraries and then share the executable file with someone that doesn't have them, will he be able to run the app without any problems?
You need to statically link to the libraries. Then there shouldn't be a problem.

If you're planning to use curses to do what you want (other that the static linking issue) look up "raw mode"

As you can see from the posts, unless your compiler has some non-standard input function this is not a simple problem. Is this really something you must have? Is the solution beyond your current ability?

The only true way to prevent them from typing it is to remove all other keys on the keyboard. Well maybe you could have a specially designed keyboard which only has one key. Or perhaps you could just glue tacks to all the other keys; but you'd still have some people that would press other keys anyway, regardless of what pain they knew they'd receive. So really, it's best to just remove all the other keys. That way they won't be tempted by the tacks, and you won't have to to through the messy costs involved with manufacturing your own keyboard.
Quzah.
Hope is the first step on the road to disappointment.
Yes that's just for compiling on another computer and you could give someone your executable and he should be able to run it but remember that ncurses is for unix systems so it won't run on Windows or a system with different endianness.
There is a getch() wrapper for gcc.

It makes some trick with termio.
See the link above. Thanks Salem to suggest me this link.
