vga_getcardinfo(3) Svgalib User Manual vga_getcardinfo(3)NAMEvga_getcardinfo - returns pointer to information about the video card.
SYNOPSIS
#include <vga.h>
vga_cardinfo *vga_getcardinfo(void);
DESCRIPTION
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 as
typedef struct {
int version;
int size;
int chipset;
int physmem;
int physmemsize;
int linearmem;
} vga_cardinfo;
The fields meaning in detail:
Basic mode details
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)
