XcmsStoreColor, XcmsStoreColors - set colors

display   Specifies the connection to the X server.

       color     Specifies the color cell and the color to store.  Values specified in this XcmsColor  structure
                 remain unchanged on return.

       colors    Specifies  the  color specification array of XcmsColor structures, each specifying a color cell
                 and the color to store in that cell.  Values specified  in  the  array  remain  unchanged  upon
                 return.

       colormap  Specifies the colormap.

       compression_flags_return
                 Returns  an  array  of  Boolean values indicating compression status.  If a non-NULL pointer is
                 supplied, each element of the array is set to True if the corresponding  color  was  compressed
                 and False otherwise.  Pass NULL if the compression status is not useful.

       ncolors   Specifies the number of XcmsColor structures in the color-specification array.

       The  XcmsStoreColor function converts the color specified in the XcmsColor structure into RGB values.  It
       then uses this RGB specification in an XColor structure, whose three flags (DoRed, DoGreen,  and  DoBlue)
       are set, in a call to XStoreColor to change the color cell specified by the pixel member of the XcmsColor
       structure.   This  pixel  value  must  be  a  valid  index for the specified colormap, and the color cell
       specified by the pixel value must be a read/write cell.  If the pixel value  is  not  a  valid  index,  a
       BadValue  error  results.   If the color cell is unallocated or is allocated read-only, a BadAccess error
       results.  If the colormap is an installed map for its screen, the changes are visible immediately.

       Note that XStoreColor has no return value; therefore, an XcmsSuccess  return  value  from  this  function
       indicates  that  the  conversion  to  RGB  succeeded and the call to XStoreColor was made.  To obtain the
       actual color stored,  use  XcmsQueryColor.   Because  of  the  screen's  hardware  limitations  or  gamut
       compression, the color stored in the colormap may not be identical to the color specified.

       XcmsStoreColor can generate BadAccess, BadColor, and BadValue errors.

       The  XcmsStoreColors function converts the colors specified in the array of XcmsColor structures into RGB
       values and then uses these RGB specifications in XColor structures, whose three  flags  (DoRed,  DoGreen,
       and DoBlue) are set, in a call to XStoreColors to change the color cells specified by the pixel member of
       the  corresponding  XcmsColor  structure.   Each  pixel  value  must  be  a valid index for the specified
       colormap, and the color cell specified by each pixel value must be a read/write cell.  If a  pixel  value
       is  not  a  valid  index, a BadValue error results.  If a color cell 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.  If the colormap is an installed map for its screen, the changes are visible immediately.

       Note  that  XStoreColors  has  no return value; therefore, an XcmsSuccess return value from this function
       indicates that conversions to RGB succeeded and the call to XStoreColors was made.  To obtain the  actual
       colors  stored,  use XcmsQueryColors.  Because of the screen's hardware limitations or gamut compression,
       the colors stored in the colormap may not be identical to the colors specified.

       XcmsStoreColors can generate BadAccess, BadColor, and BadValue errors.

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.

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