XSetCloseDownMode(3X11) XLIB FUNCTIONS XSetCloseDownMode(3X11)
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 Retain-
Permanent 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 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 2.5). This permits imple-
mentation 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 win-
dows.
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 gen-
erate this error.
