NAME

vga_getpalvec - gets colors from the color lookup table  

SYNOPSIS

#include <vga.h>

int vga_getpalvec(int start, int num, int *pal);

 

DESCRIPTION

Gets the num colors starting with index start from the color lookup table and stores the RGB values in *pal. *pal contains 3 * num integers which are the color values from first to last palette entry in the order red, green, blue (always three consecutive entries in *pal built a palette entry.

Each color entry is in range 0 - 63. This function is only sensible in 16 or 256 color modes. It shows which color all vga_setcolor(start) (and num - 1 following colors) drawn pixels will actually refer to.

If the VGA_CLUT8 feature is set for the current mode with vga_ext_set(3) the red, green, and blue values are in the range 0 - 255.

The function returns the value of num.

This manual page was edited by Michael Weller <eowmob@exp-math.uni-essen.de>. The exact source of the referenced function as well as of the original documentation is unknown.

It is very likely that both are at least to some extent are due to Harm Hanemaayer <H.Hanemaayer@inter.nl.net>.

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.
