int version;
int size;
int chipset;

} vga_cardinfo;

The fields meaning in detail:

Basic mode details

Version of the information structure. Application can use this field to make sure the data it needs is really there.
Size of the cardinfo structure. The structure is malloc()ed, and the program should free it when no longer needed.
Number of the chispet driver used to drive the card. Same list as is used in the vga_setchipset function.
Physical address of the linear memory aperture of the card. This is needed for example for setting the video overlay of v4l devices.
Amount of physical memory in bytes. (Version >= 0x0200)
Virtual address of the linear memory aperture. Please note that currently it is mapped at vga_init, but in future versions of svgalib this might change. (Version >= 0x0200)
