XcmsAllocColor()														  XcmsAllocColor()

Name
  XcmsAllocColor - allocate a color specified in device-independent or device-dependent form.

Synopsis
  Status XcmsAllocColor(display, colormap, color_in_out, result_format)
	Display *display;
	Colormap colormap;
	XcmsColor *color_in_out;
	XcmsColorFormat result_format;

Arguments
  display   Specifies the connection to the X server.

  colormap  Specifies the colormap.

  color_in_out
	    Specifies the color to allocate and returns the pixel and color that is actually used in the colormap.

  result_format
	    Specifies the desired color format for the returned color specification.

Returns
  Zero on failure, non-zero on success.

Availability
  Release 5 and later.

Description
  The XcmsAllocColor() function is similar to XAllocColor() except the color can be specified in any format supported by the color management
  system (e.g., CIEXYZ, CIELUV, RGB).  The XcmsAllocColor() function ultimately calls XAllocColor() to allocate a read-only color cell	(col-
  ormap entry) with the specified color.  XcmsAllocColor() first converts the color specified to an RGB value and then passes this to XAlloc-
  Color.  XcmsAllocColor() returns the pixel value of the color cell and the color specification actually  allocated.	This  returned	color
  specification  is the result of converting the RGB value returned by XAllocColor() into the format specified by the result_format argument.
  If there is no interest in a returned color specification, unnecessary computation can be bypassed if result_format is set  to  XcmsRGBFor-
  mat.	If this routine returns XcmsFailure, the color_in_out color specification is left unchanged.

Structures
  The XcmsColor and XcmsColorFormat structures are shown on the XcmsColor reference page.

Errors
  BadColor  The colormap argument does not name a defined Colormap.
