SVGALib

SVGAlib is an open-source low-level graphics library which runs on Linux and FreeBSD and allows programs to change video mode and display full-screen graphics. Some popular games like "Quake" and "Doom" used it in their original releases.

The library was popular in mid-1990s. Toward 2000, many applications that used it migrated to X11 and SDL, which itself can make use of SVGAlib as a video driver.

A sample of SVGAlib code is shown below.

#include
#include
#include

int main(void){ int color = 4; int x = 10; int y = 10; unsigned int seconds = 5;

/* detect the chipset and give up supervisor rights */ if (vga_init() < 0) return EXIT_FAILURE;

vga_setmode(G320x200x256); vga_setcolor(color); vga_drawpixel(x, y); sleep(seconds); /* restore textmode and fall back to ordinary text console handling */ vga_setmode(TEXT); return EXIT_SUCCESS;}
