gl_getpalettecolor(3) Svgalib User Manual gl_getpalettecolor(3)NAME
gl_getpalettecolor, gl_getpalettecolors, gl_getpalette - read the color palette
SYNOPSIS
#include <vgagl.h>
void gl_getpalettecolor(int c, int *r, int *g, int *b);
void gl_getpalettecolors(int s, int n, void *dp);
void gl_getpalette(void *dp);
DESCRIPTION
gl_getpalettecolor gets red, green and blue values (in the range 0 - 63) of color c from the color-lookup-table, and stores them as inte-
gers in the memory locations pointed to by r, g and b.
gl_getpalettecolors gets RGB values of n colors starting at s, which are stored as a table of groups of three bytes each at dp.
gl_getpalette is equivalent to getpalettecolors(0, 256, dp).
vga_ext_set(3) might change the range of the colors returned to 0 - 255.

keyboard_init(3) Svgalib User Manual keyboard_init(3)NAME
keyboard_init, keyboard_init_return_fd - initialize the keyboard to raw mode
SYNOPSIS
#include <vgakeyboard.h>
int keyboard_init(void);
int keyboard_init_return_fd(void);
DESCRIPTION
These routines initialize the keyboard to raw mode. No ASCII codes are produced, instead svgalib keeps track of each single keypress or
depress. The return_fd version returns the file descriptor of the console device to allow you to do further tricks with it (though it is
unclear which). The other version just returns 0 if successful. Both return -1 on error.
keyboard_close(3) returns to normal operation.
When in raw keyboard mode you can no longer use vga_getch(3) or vga_getkey(3) but you must use keyboard_getstate(3) or keyboard_key-
pressed(3).
Depending on the setting of keyboard_translatekeys(3) even in raw mode a <Ctrl>-C will cause a SIGINT. In any case svgalib will check for
<Alt>-F1 - <Alt>-F10 and perform console switches accordingly.
