Name
       DwtCopyFromClipboard - Retrieves a data item from the clipboard.

Syntax
       int DwtCopyFromClipboard(display, window, format_name,
				buffer, length,
				num_bytes, private_id)
	    Display *display;
	    Window window;
	    char *format_name;
	    char *buffer;
	    unsigned long length;
	    unsigned long *num_bytes;
	    int *private_id;

Arguments
       display	 Specifies  a pointer to the Display structure that was returned in a previous call to XOpenDisplay.  For information on XOpenDis-
		 play and the Display structure, see the Guide to the Xlib Library: C Language Binding.

       window	 Specifies the window ID that relates the application window to the clipboard.	The same application instance should pass the same
		 window ID to each clipboard function that it calls.

       format_name
		 Specifies the name of a format in which the data is stored on the clipboard.

       buffer	 Specifies the buffer to which the application wants the clipboard to copy the data.

       length	 Specifies the length of the application buffer.

       num_bytes Specifies the number of bytes of data copied into the application buffer.

       private_id
		 Specifies  the  private  data	stored	with  the data item by the application that placed the data item on the clipboard.  If the
		 application did not store private data with the data item, this argument returns zero.

Description
       The DwtCopyFromClipboard function retrieves the current next-paste item from clipboard storage.

       DwtCopyFromClipboard returns a warning under the following circumstances:

       o    The data needs to be truncated because the buffer length is too short

       o    The clipboard is locked

       o    There is no data on the clipboard

Return Values
       This function returns one of these status return constants:

       ClipboardSuccess    All data on the clipboard
			   has	been copied success-
			   fully.  A successful copy
			   can	be a one-time opera-
			   tion  using	DwtCopyFrom-
			   Clipboard  alone,  or  an
			   incremental	   operation
			   using  multiple  calls to
			   DwtCopyFromClipboard
			   between   calls  to	Dwt-
			   StartCopyFromClipboard
			   and	 DwtEndCopyFromClip-
			   board.
       ClipboardLocked	   The	  function    failed
			   because the clipboard was
			   locked by another  appli-
			   cation.   The application
			   can continue to call  the
			   function  with  the	same
			   parameters	until	 the
			   clipboard   is  unlocked.
			   Optionally, the  applica-
			   tion  can ask if the user
			   wants to keep  trying  or
			   to  give up on the opera-
			   tion.
       ClipboardTruncate   If using DwtCopyFromClip-
			   board   alone,  the	data
			   returned   is   truncated
			   because  the user did not
			   provide a buffer that was
			   large  enough to hold the
			   data.  If using  multiple
			   calls to DwtCopyFromClip-
			   board in between calls to
			   DwtStartCopyFromClipboard
			   and	 DwtEndCopyFromClip-
			   board,  more  data in the
			   requested format  remains
			   to  be  copied  from  the
			   clipboard.
       ClipboardNoData	   The	function  could  not
			   find  data  on  the clip-
			   board  corresponding   to
			   the	 format   requested.
			   This could occur because:(1)	 the   clipboard  is
			   empty; (2) there is	data
			   on  the clipboard but not
			   in the requested  format;
			   and(3)  the data in the
			   requested   format	 was
			   passed  by name and is no
			   longer available.
