NAME
     XSetCloseDownMode, XKillClient - control clients

SYNTAX
     XSetCloseDownMode(display, close_mode)
           Display *display;
           int close_mode;

     XKillClient(display, resource)
           Display *display;
           XID resource;

ARGUMENTS
     close_mode
               Specifies the client close-down mode.  You can
               pass DestroyAll, RetainPermanent, or RetainTem-
               porary.

     display   Specifies the connection to the X server.

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

DESCRIPTION
     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 Retain-
     Permanent or RetainTemporary, see section 2.6.

     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 RetainPer-
     manent or RetainTemporary mode, all of the client's
     resources are destroyed.  If AllTemporary is specified, the
     resources of all clients that have terminated in RetainTem-
     porary are destroyed (see section 2.6).  This permits imple-
     mentation 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 win-
     dows.

     XKillClient can generate a BadValue error.

DIAGNOSTICS
     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
