Some popular games like Quake and Doom have been ported to use SVGAlib. HistoryThe library was popular in mid-1990s.{{citation needed|date=October 2016}} Toward 2000, many applications that used it migrated to X11 and SDL{{citation needed|date=October 2016}}, which itself can make use of SVGAlib as a video driver. SampleA sample of SVGAlib code is shown below.
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); /* restore textmode and fall back to ordinary text console handling */ vga_setmode(TEXT); } See also{{Portal|Free and open-source software}}
