XSetCloseDownMode(3X11) X11 SDE 5.4R3.00 XSetCloseDownMode(3X11)
NAME
XSetCloseDownMode, XKillClient - control clients
SYNTAX
XSetCloseDownMode(display, closemode)
Display *display;
int closemode;
XKillClient(display, resource)
Display *display;
XID resource;
ARGUMENTS
closemode
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.
