'''svgalib'''是一套運行於[[Linux]]及[[FreeBSD]]下的[[開放原始碼]]低階繪圖[[函式庫]]，它允許程式設計人員變更視訊模式及全螢幕圖像，許多熱門的電腦遊戲如''[[Quake]]''及''[[Doom]]''都源自此技術。<br />
<br />
svgalib在1990年代中期開始並遍，但到2000年之後，多數使用此技術的應用都漸次轉移到了[[X Window System|X11]] and [[SDL]]（Simple DirectMedia Layer）上。<br />
<br />
本函式庫很容易使用，可以參考以下程式範例片段：<br />
<br />
<syntaxhighlight lang="c"> <br />
#include <stdlib.h><br />
#include <unistd.h><br />
#include <vga.h><br />
<br />
int main(void)<br />
{<br />
int color = 4;<br />
int x = 10;<br />
int y = 10;<br />
unsigned int seconds = 5;<br />
<br />
/* detect the chipset and give up supervisor rights */<br />
if (vga_init() < 0)<br />
return EXIT_FAILURE;<br />
<br />
vga_setmode(G320x200x256);<br />
vga_setcolor(color);<br />
vga_drawpixel(x, y);<br />
<br />
sleep(seconds);<br />
<br />
/* restore textmode and fall back to ordinary text console handling */<br />
vga_setmode(TEXT);<br />
<br />
return EXIT_SUCCESS;<br />
}<br />
</syntaxhighlight><br />
