NAME

       XSetCloseDownMode, XKillClient - control clients

SYNTAX

       int XSetCloseDownMode(Display *display, int close_mode);

       int XKillClient(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 2.5).  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.

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.
