XStoreColors(3X11)	       XLIB FUNCTIONS		   XStoreColors(3X11)



NAME
  XStoreColors, XStoreColor, XStoreNamedColor - set colors

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

  XStoreColor(display, colormap, color)
	Display *display;
	Colormap colormap;
	XColor *color;

  XStoreNamedColor(display, colormap, color, pixel, flags)
	Display *display;
	Colormap colormap;
	char *color;
	unsigned long pixel;
	int flags;

ARGUMENTS

  color	    Specifies the pixel and RGB values or the color name string (for
	    example, red).

  color	    Specifies an array of color definition structures to be stored.

  colormap  Specifies the colormap.

  display   Specifies the connection to the X server.

  flags	    Specifies which red, green, and blue components are set.

  ncolors   Specifies the number of XColor structures in the color definition
	    array.

  pixel	    Specifies the entry in the colormap.

DESCRIPTION
  The XStoreColors function changes the colormap entries of the pixel values
  specified in the pixel members of the XColor structures.  You specify which
  color components are to be changed by setting DoRed, DoGreen, and/or DoBlue
  in the flags member of the XColor structures.	 If the colormap is an
  installed map for its screen, the changes are visible immediately.
  XStoreColors changes the specified pixels if they are allocated writable in
  the colormap by any client, even if one or more pixels generates an error.
  If a specified pixel is not a valid index into the colormap, a BadValue
  error results.  If a specified pixel either is unallocated or is allocated
  read-only, a BadAccess error results.	 If more than one pixel is in error,
  the one that gets reported is arbitrary.

  XStoreColors can generate BadAccess, BadColor, and BadValue errors.

  The XStoreColor function changes the colormap entry of the pixel value
  specified in the pixel member of the XColor structure.  You specified this
  value in the pixel member of the XColor structure.  This pixel value must
  be a read/write cell and a valid index into the colormap.  If a specified
  pixel is not a valid index into the colormap, a BadValue error results.
  XStoreColor also changes the red, green, and/or blue color components.  You
  specify which color components are to be changed by setting DoRed, DoGreen,
  and/or DoBlue in the flags member of the XColor structure.  If the colormap
  is an installed map for its screen, the changes are visible immediately.

  XStoreColor can generate BadAccess, BadColor, and BadValue errors.

  The XStoreNamedColor function looks up the named color with respect to the
  screen associated with the colormap and stores the result in the specified
  colormap.  The pixel argument determines the entry in the colormap.  The
  flags argument determines which of the red, green, and blue components are
  set. You can set this member to the bitwise inclusive OR of the bits DoRed,
  DoGreen, and DoBlue.	If the color name is not in the Host Portable Charac-
  ter Encoding, the result is implementation dependent.	 Use of uppercase or
  lowercase does not matter.  If the specified pixel is not a valid index
  into the colormap, a BadValue error results.	If the specified pixel either
  is unallocated or is allocated read-only, a BadAccess error results.

  XStoreNamedColor can generate BadAccess, BadColor, BadName, and BadValue
  errors.

DIAGNOSTICS

  BadAccess A client attempted to free a color map entry that it did not
	    already allocate.

  BadAccess A client attempted to store into a read-only color map entry.

  BadColor  A value for a Colormap argument does not name a defined Colormap.

  BadName   A font or color of the specified name does not exist.

  BadValue  Some numeric value falls outside the range of values accepted by
	    the request.  Unless a specific range is specified for an argu-
	    ment, the full range defined by the argument's type is accepted.
	    Any argument defined as a set of alternatives can generate this
	    error.
