The Turbo C (Borland C), comes with a set of graphics drivers and api called the BGI (Borland Graphics Interface)., this provides the header graphics.h and a couple of libraries which make it possible to program graphics on M$DOS. This feature is not available on any other C compiler. For example DOS based Watcom compilers had a different way of graphic programming. On GNU/Linux and UNIXes in general, graphic programming is done through the X Server. There are numerous policies in programming the GUI on the UNIXes. You can choose to program on some window manager such as Qt or Gtk+., or you may program directly at the X Window level. When using Windowmanager, you get to create windows.. when programming at the X-window level., you get to draw pixels and lines directly on the screen Cheers, Joe -- A proud GNU user http://www.joesteeve.tk/ | http://gnukid.shyper.com/
