XSetCloseDownMode(XS) X Version 11 (Release 5) XSetCloseDownMode(XS)
6 January 1993
Name
XSetCloseDownMode - control clients
Syntax
XSetCloseDownMode(display, close_mode)
Display *display;
int close_mode;
XKillClient(display, resource)
Display *display;
XID resource;
Arguments
closemode Specifies the client close-down mode. You can pass De-
stroyAll, 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 infor-
mation on what happens to the client's resources when the closemode
argument is RetainPermanent or RetainTemporary, see section 2.6 of 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 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 de-
stroyed (see section 2.5 of 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 de-
stroy 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 speci-
fied 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.
