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.

NAME

       restorepalette - set the color palette for textmode.

SYNOPSIS

       restorepalette [filename]

DESCRIPTION

       restorepalette without arguments sets the standard VGA palette. This can be useful if it is somehow messed up.

       With a filename argument a custom palette can be loaded (feature added by Charles Blake <chuckb@alice.wonderland.caltech.edu>).

       This  allow  a  user to set up a file that looks like this one (These color map definitions are the same as the default VGA ones.  Alter to
       suite personal tastes). The first column contains the number of the color to set, then follow three integers in range 0	-  63  (lowest	to
       highest intensity) for red, green, blue.

	       0  0  0	0   # black
	       1  0  0 42   # blue
	       2  0 42	0   # green
	       3  0 42 42   # cyan
	       4 42  0	0   # red
	       5 42  0 42   # magenta
	       6 42 21	0   # brown
	       7 42 42 42   # white
	       8 21 21 21   # bright black
	       9 21 21 63   # bright blue
	      10 21 63 21   # bright green
	      11 21 63 63   # bright cyan
	      12 63 21 21   # bright red
	      13 63 21 63   # bright magenta
	      14 63 63 21   # bright brown
	      15 63 63 63   # bright white

       The  inline  comments are the only kind of allowed, as I use a little fscanf(3) trick to get them. Blank lines are ok, but not pure comment
       lines. See the comments in my code, also.

       This allows people to set up custom palettes for use in virtual console text modes. I use it all the time. When combined with a	color-syn-
       tax  editor  like  jed-0.97+  or  color-ls,  etc.,  being  able	to  choose  your own text-mode palette is quite a bonus. I set mine up via
       restorepalette /etc/palette in my /etc/rc.  If the program is given the correct permissions, then individual users can have  restorepalette
       ~/.palette  or  some such thing in their shell startup files.  Of course, it shouldn't be done when starting remote shells or when under X,
       so some kind of test that TERM is a virtual console is needed for that case.
