XSetCloseDownMode, XKillClient
- control clients
- int XSetCloseDownMode(Display *display, int close_mode);
- int XKillClient(Display *display, XID resource);
- 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.
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.
- 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.
