vga_getcardinfo(3) - Linux man page

Name

vga_getcardinfo - returns pointer to information about the video card.

#include <vga.h>

vga_cardinfo *vga_getcardinfo(void);

The function returns a pointer to a card information structure which is filled out with details about the video card in use.

#include <vga.h> defines vga_cardinfo

typedef struct {
int version;
int size;
int chipset;
int physmem;
int physmemsize;
int linearmem;
} vga_cardinfo;

The fields meaning in detail:

version: Version of the information structure. Application can use this field to make sure the data it needs is really there.
size: Size of the cardinfo structure. The structure is malloc()ed, and the program should free it when no longer needed.
chipset: Number of the chispet driver used to drive the card. Same list as is used in the vga_setchipset function.
physmem: Physical address of the linear memory aperture of the card. This is needed for example for setting the video overlay of v4l devices.
physmemsize: Amount of physical memory in bytes. (Version >= 0x0200)
linearmem: 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)
