From the original Amiga UNIX 2.1 manual. Some things it mentions may not be in this release.

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 XWIN 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, Xlib-C
Language X Interface.

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, Xlib-C Language X
Interface).  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.
