XSetCloseDownMode(3) XLIB FUNCTIONS XSetCloseDownMode(3)
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 Destroy-
All, 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 in-
formation 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 al-
ready 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 man-
ager 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 ac-
cepted. Any argument defined as a set of alternatives can
generate this error.
