XStoreColors()							XStoreColors()

Name
  XStoreColors – set or change the RGB values of read/write colorcells to
  the closest possible hardware colors.

Synopsis
  XStoreColors(display, colormap, color, ncolors)
	Display *display;
	Colormap colormap;
	XColor color[ncolors];
	int ncolors;

Arguments
  display  Specifies a connection to an X server; returned from XOpenDis‐
	   play().

  colormap
	   Specifies the colormap.

  color	   Specifies an array of color definition structures.

  ncolors  Specifies the number of XColor structures in color.

Description
  XStoreColors()  changes the RGB values of each colormap entry specified
  by color[].pixel to the closest possible hardware colors.   Each  pixel
  value	 must  be  a  read/write  cell	and  a valid index into colormap.
  XStoreColors() changes the red, green, and/or blue color components  in
  each cell according to the color[].flags member, which you set by ORing
  the constants DoRed, DoGreen, and/or DoBlue.	The specified pixels  are
  changed  if they are writable by any client, even if one or more pixels
  generates an error.

  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  A specified pixel is not a valid entry into colormap.
