To start, you need to set the video mode. And that means DOS conio programs can easily access video modes and leverage screen regions in ways that are difficult using Linux ncurses. On DOS, everything is running on hardware. This is different from the ncurses library on Linux, where everything is displayed through terminal emulation. Setting the video modeĮverything you do is immediately displayed on-screen via hardware. Let's get started with the OpenWatcom conio functions. Because the OpenWatcom C Compiler has been used for a long time by many developers, this conio implementation is also quite popular.

OpenWatcom supports its own version of conio, implemented in conio.h for particular console input and output functions, and in graph.h to set colors and perform other manipulation.Try for free: Red Hat Learning Subscription.Some minor tweaks may be required to run the code.
