SYNOPSIS

12
13       void gl_getpalettecolor(int c, int *r, int *g, int *b);
14       void gl_getpalettecolors(int s, int n, void *dp);

DESCRIPTION

19       gl_getpalettecolor gets red, green and blue values (in the  range  0  -
20       63) of color c from the color-lookup-table, and stores them as integers
21       in the memory locations pointed to by r, g and b.
22
23       gl_getpalettecolors gets RGB values of n colors starting  at  s,  which
24       are stored as a table of groups of three bytes each at dp.
25
26       gl_getpalette is equivalent to getpalettecolors(0, 256, dp).
27
28       vga_ext_set(3)  might  change  the  range of the colors returned to 0 -
29       255.
