X Version 11 (1 September 1988) XSetCloseDownMode(XS)
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
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 2.6). 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.
