C: Getting a char from keyboard without enter?

I am using a linux box Red Hat 8.0, and need to write a small C prog that gets a single char from the keyboard without pressing enter.

On some platforms getch() (from connio.h) does this, but this does not exist on the box I am using?

What header file doe I need in Linux and what function do I need to use??

Thanks,

Lloyd

It doesn't appear that linux is capable of that in it's default mode. check out this link to find out why:http://www.ale.org/archive/ale/ale-2000-07/msg00442.html

Thanks for the link - at least I now know the problem, but for some reason I can't get that code compiling on my Linux box.

You could use ncurses.
Btw why is it so important that you don't have to press enter?If you use the C++ function getline,you can speficy some other character than return.
