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 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.

       original	documentation is unknown.

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