XSetCloseDownMode(3X11)              BSD               XSetCloseDownMode(3X11)



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 RetainTemporary.

     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 RetainPermanent 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 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 2.6).  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.

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 defined by the argument's type is
               accepted.  Any argument defined as a set of alternatives can
               generate this error.
