NAME

       XcmsAllocColor, XcmsAllocNamedColor - allocate colors

SYNOPSIS

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

       Status XcmsAllocNamedColor(display, colormap, color_string, color_screen_return, color_exact_return, result_format)
	       Display *display;
	       Colormap colormap;
	       char *color_string;
	       XcmsColor *color_screen_return;
	       XcmsColor *color_exact_return;
	       XcmsColorFormat result_format;

ARGUMENTS

       Specifies  the connection to the X server.  Specifies the colormap.  Returns the color specification parsed from the color string or parsed
       from the corresponding string found in a color name database.  Specifies the color to allocate and returns the  pixel  and  color  that	is
       actually  used  in  the colormap.  Returns the pixel value of the color cell and color specification that actually is stored for that cell.
       Specifies the color string whose color definition structure is to be returned.  Specifies the color format for the returned color  specifi-
       cation.

DESCRIPTION

       The  XcmsAllocColor  function  is similar to XAllocColor except the color can be specified in any format. The XcmsAllocColor function ulti-
       mately calls XAllocColor to allocate a read-only color cell (colormap entry) with the specified color.  XcmsAllocColor first  converts  the
       color  specified  to  an  RGB  value and then passes this to XAllocColor.  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 with the result_format argument. If there is no interest in a returned color specification, unnecessary computa-
       tion can be bypassed if result_format is set to XcmsRGBFormat. The corresponding colormap cell is read-only. If this routine returns  Xcms-
       Failure, the color_in_out color specification is left unchanged.

       XcmsAllocColor can generate a BadColor errors.

       The  XcmsAllocNamedColor  function  is  similar to XAllocNamedColor except the color returned can be in any format specified. This function
       ultimately calls XAllocColor to allocate a read-only color cell with the color specified by a color string.  The  color	string	is  parsed
       into an XcmsColor structure (see XcmsLookupColor(3X11)), converted to an RGB value, and finally passed to XAllocColor. If the color name is
       not in the Host Portable Character Encoding, the result is implementation dependent.  Use of uppercase or lowercase does not matter.

       This function returns both the color specification as a result of parsing (exact specification) and the actual color  specification  stored
       (screen specification).	This screen specification is the result of converting the RGB value returned by XAllocColor into the format speci-
       fied in result_format.  If there is no interest in a returned color specification, unnecessary computation can be bypassed if result_format
       is  set to XcmsRGBFormat.  If color_screen_return and color_exact_return point to the same structure, the pixel field will be set correctly
       but the color values are undefined.

       XcmsAllocNamedColor can generate a BadColor errors.

DIAGNOSTICS

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