XtCancelConvertSelectionProc()											    XtCancelConvertSelectionProc()

Name
  XtCancelConvertSelectionProc - interface definition for procedure to cancel incremental selection transfer.

Synopsis
  typedef void (*XtCancelConvertSelectionProc)(Widget, Atom*, Atom*,
  XtRequestId*, XtPointer);
	 Widget w;
	 Atom *selection;
	 Atom *target;
	 XtRequestId *request_id;
	 XtPointer client_data;

Inputs
  w	    Specifies the widget that owns the selection.

  selection Specifies the atom that names the selection being transferred.

  target    Specifies the target type to which the conversion was done.

  request_id
	    Specifies an opaque identification for a specific request.

  client_data
	    Specifies the value passed in by the widget when it took ownership of the selection.

Availability
  Release 4 and later.

Description
  This	procedure  is  registered  in a call to XtOwnSelectionIncremental(), and is called by the Intrinsics to abort an incremental transfer
  when (as determined by the selection timeout or other mechanism) any remaining segments of the selection no longer need to be  transferred.
  Upon	receiving  this  callback,  the selection request is considered complete and the owner should free the memory and any other resources
  that have been allocated for the transfer.

  The w, selection, and client_data arguments are those passed in the call to XtOwnSelectionIncremental().  The target and  request_id	argu-
  ments  are  the  selection target type specified by the selection requestor, and the unique ID assigned to this transfer by the Intrinsics.
  Both will have been passed to a previous call to the XtConvertSelectionIncrProc also registered with XtOwnSelectionIncremental().

Name
  XtSelectionDoneIncrProc - interface definition for procedure called when an incremental selection transfer completes.

Synopsis
  typedef void (*XtSelectionDoneIncrProc)(Widget, Atom *, Atom *,
  XtRequestId *, XtPointer);
	 Widget w;
	 Atom *selection;
	 Atom *target;
	 XtRequestId *request_id;
	 XtPointer client_data;

Inputs
  w	    Specifies the widget that owns the selection.

  selection Specifies the atom that names the selection being transferred.

  target    Specifies the target type to which the conversion was done.

  request_id
	    Identifies the specific conversion request that completed.

  client_data
	    Specifies data registered with this procedure when the widget took ownership of the selection.

Availability
  Release 4 and later.

Description
  An  XtSelectionDoneIncrProc  is  optionally  registered in a call to XtOwnSelectionIncremental(), and is called by the Intrinsics after the
  requestor has retrieved the final (zero-length) segment of the incremental transfer to indicate that the entire transfer is complete.   The
  w,  selection,  and  client_data  arguments are those passed to XtOwnSelectionIncremental().	The target and request_id arguments are those
  that were passed to the XtConvertSelectionIncrProc registered with this procedure.

  An XtSelectionDoneIncrProc should free any memory that was allocated for the transfer of the selection value.  If no	procedure  is  speci-
  fied,  the Intrinsics will automatically free (using XtFree()) the last value returned by the XtConvertSelectionIncrProc.  If a single buf-
  fer is used to transfer all the chunks of the selection, this automatic freeing by the Intrinsics should be sufficient.  If  separate  buf-
  fers	are used or other memory or resources are allocated to transfer the selection value, an XtSelectionDoneIncrProc should be provided to
  free them.

Usage
  It is usually more convenient to use the Intrinsics atomic selection transfer mechanism which transfers the selection  value	in  a  single
  chunk.  See XtOwnSelection(1) and XtSelectionDoneProc for more information.
