XStoreColor()							 XStoreColor()

Name
  XStoreColor  –  set  or  change the RGB values of a read/write colormap
  entry to the closest possible hardware color.

Synopsis
  XStoreColor(display, cmap, colorcell_def)
	Display *display;
	Colormap cmap;
	XColor *colorcell_def;

Arguments
  display     Specifies a  connection  to  an  X  server;  returned  from
	      XOpenDisplay().

  cmap	      Specifies the colormap.

  colorcell_def
	      Specifies a pixel value and the desired RGB values.

Description
  XStoreColor()	 changes  the RGB values of a colormap entry specified by
  colorcell_def.pixel to the closest values  possible  on  the	hardware.
  This pixel value must be a read/write cell and a valid index into cmap.
  XStoreColor() changes the red, green, and/or blue color  components  in
  the  cell according to the colorcell_def.flags member, which you set by
  ORing the constants DoRed, DoGreen, and/or DoBlue.

  If the colormap is an installed map for its  screen,	the  changes  are
  visible immediately.

  For more information, see Volume One, Chapter 7, Color.

Structures
     typedef struct {
	 unsigned long pixel;
	 unsigned short red, green, blue;
	 char flags;	/* DoRed, DoGreen, DoBlue */
	 char pad;
     } XColor;

Errors
  BadAccess A specified pixel is unallocated or read-only.

  BadColor  Invalid colormap.

  BadValue  pixel not valid index into cmap.
