       XSetCloseDownMode, XKillClient - control clients


       int XSetCloseDownMode(Display *display, int close_mode);

       int XKillClient(Display *display, XID resource);


                 Specifies the client close-down mode.  You can pass
                 DestroyAll, RetainPermanent, or RetainTemporary.

       display   Specifies the connection to the X server.

       resource  Specifies any resource associated with the client that you
                 want to destroy or AllTemporary.


       The XSetCloseDownMode defines what will happen to the client's
       resources at connection close.  A connection starts in DestroyAll mode.
       For information on what happens to the client's resources when the
       close_mode argument is RetainPermanent or RetainTemporary, see section

       XSetCloseDownMode can generate a BadValue error.

       The XKillClient function forces a close down of the client that created
       the resource if a valid resource is specified.  If the client has
       already terminated in either RetainPermanent or RetainTemporary mode,
       all of the client's resources are destroyed.  If AllTemporary is
       specified, the resources of all clients that have terminated in
       RetainTemporary are destroyed (see section 2.5).  This permits
       implementation of window manager facilities that aid debugging.  A
       client can set its close-down mode to RetainTemporary.  If the client
       then crashes, its windows would not be destroyed.  The programmer can
       then inspect the application's window tree and use the window manager
       to destroy the zombie windows.

       XKillClient can generate a BadValue error.


       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.
