trusty (3) gl_getpalette.3.gz

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 integers 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.
