ARGUMENTS

       display   Specifies the connection to the X server.

       owner     Specifies the owner of the specified selection
                 atom.  You can pass a window or None.

       property  Specifies the property name.  You also can pass
                 None.

       requestor Specifies the requestor.

       selection Specifies the selection atom.

       target    Specifies the target atom.

       time      Specifies the time.  You can pass either a
                 timestamp or CurrentTime.


DESCRIPTION

       The XSetSelectionOwner function changes the owner and
       last-change time for the specified selection and has no
       effect if the specified time is earlier than the current
       last-change time of the specified selection or is later
       than the current X server time.  Otherwise, the last-
       change time is set to the specified time, with CurrentTime
       replaced by the current server time.  If the owner window
       is specified as None, then the owner of the selection
       becomes None (that is, no owner).  Otherwise, the owner of
       the selection becomes the client executing the request.

       errors.

       The XGetSelectionOwner function returns the window ID
       associated with the window that currently owns the speci-
       fied selection.  If no selection was specified, the func-
       tion returns the constant None.  If None is returned,
       there is no owner for the selection.

       XGetSelectionOwner can generate a BadAtom error.

       XConvertSelection requests that the specified selection be
       converted to the specified target type:

       o    If the specified selection has an owner, the X server
            sends a SelectionRequest event to that owner.

       o    If no owner for the specified selection exists, the X
            server generates a SelectionNotify event to the
            requestor with property None.

       The arguments are passed on unchanged in either of the
       events.  There are two predefined selection atoms: PRIMARY
       and SECONDARY.

       XConvertSelection can generate BadAtom and BadWindow
       errors.


DIAGNOSTICS

       BadAtom   A value for an Atom argument does not name a
                 defined Atom.

       BadWindow A value for a Window argument does not name a
                 defined Window.
