    Question 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?

    Talking thankx

    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.
