XCopyColormapAndFree()													    XCopyColormapAndFree()

Name
  XCopyColormapAndFree - copy a colormap and return a new colormap ID.

Synopsis
  Colormap XCopyColormapAndFree(display, colormap)
	Display *display;
	Colormap colormap;

Arguments
  display   Specifies a connection to an X server; returned from XOpenDisplay().

  colormap  Specifies the colormap you are moving out of.

Returns
  The created colormap.

Description
  XCopyColormapAndFree()  is  used  to	obtain a new virtual colormap when allocating colorcells out of a previous colormap has failed due to
  resource exhaustion (that is, too many cells or planes were in use in the original colormap).  The visual and screen for the	new  colormap
  is the same as for the old.

  XCopyColormapAndFree()  moves all of the client's existing allocations from colormap to the returned Colormap.  The read/write or read-only
  characteristics of each cell moved are preserved in the new colormap.

  If colormap was created by the client with the alloc argument set to AllocAll, the new colormap is also created with	AllocAll,  all	color
  values for all entries are copied from colormap, and then all entries in colormap are freed.

  If  colormap	was  created by the client with AllocNone, or not created by the client, the allocations to be moved are all those pixels and
  planes that have been allocated by the client using XAllocColor, XAllocNamedColor(), XAllocColorCells(), or  XAllocColorPlanes()  and  that
  have not been freed since they were allocated.  Values in other entries of the new Colormap are undefined.

  For more information, see Volume One, Chapter 7, Color.

Errors
  BadAlloc

  BadColor  colormap is invalid.
