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.
