XSetCloseDownMode(3)


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.
