XSetCloseDownMode(3X11) X Version 11(Release 5) XSetCloseDownMode(3X11)
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 2.5). 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.
