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.
