Unix and keystrokes

[Amit Agrawal]

I want to write a program in C++ which shall run on linux. I want to capture the keystokes as the key is pressed without the necessity of hitting return/enter.

What is the function I should use?

Either getc() or getch() should work, I believe they will read in without needing a return?

Otherwise, this problem can be tougher. Usually in C++ I use my own x86 keyboard handler so as to have more control over keys, so I'm not familiar with linux or with typical get character functions.

The functions suggested are found only in the conio.h which is not available in UNIX env.

You can use the curses library. It has a getch() that will allow you to do this.
getc(), as suggested before, requires you to hit return, so you can't use it.

To use the curses library, see this page: http://www.ecks.org/docs/ncurses-intro.html

Use cin.get. It is in iostream.h
