History
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.
Sample
A sample of SVGAlib code is shown below:
#include <stdlib.h>
#include <unistd.h>
#include <vga.h>
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;
}
