gl_getpalettecolor(3)         Svgalib User Manual        gl_getpalettecolor(3)

       gl_getpalettecolor, gl_getpalettecolors, gl_getpalette - read the color

       #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);

       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 -

       svgalib(7), vgagl(7), svgalib.conf(5), threedkit(7), testgl(1),
       vga_ext_set(3), gl_setpalette(3), gl_setpalettecolor(3),

       It is very likely that both are at least to some extent are due to Harm

       Occasionally this might be wrong. I hereby asked to be excused by the
       original author and will happily accept any additions or corrections to
       this first version of the svgalib manual.
