How do I use graphics libaries in Linux C/C++?

I'm currently learning C in a Linux OS but I've already learned a lot of C++ in MSV 6.0. The question is though, how do I use graphics and their libraries in Linux C and MSV C++ and how do I translate the C++ command: flush, in Linux C. Can anybody help me along with some info. I need it to start on my case study.

Well, if you use the Allegro library (graphics/sound/input), you don't have to change a single line of code to compile for MSVC in Windows and GCC in Linux. :) flush() is a standard C function and is thus also available in both platforms. Have you had trouble getting it to work?

the tips that you gave me worked really well. but the flush i was referring to is in C++ it would be somnething like:

//move to a section on the screen using x,y
//set bg to a color
cout << " " << flush;

From previous experience, the << flush kept the color from over flowing from the space instead of covering the whole line:

// color below w/ flush and 5 spaces

*****_

// without flush and 5 spaces
***********************
_

it covers the whole line of a screen instead of stopping

So.. your trying to find a C equiv? ('Cause Linux doesn't have any problems with C++..) Well, you won't be using cout at all then either I suppose, so it depends. For text stuff, use printf() (and its variants) and don't worry about flush because printf() is low level enough not to need it.

Hope that helps.

EDIT: Also see the curses library which allows for all sorts of fancy text stuff.
