Specifies the client close-down mode. You can pass DestroyAll, RetainPermanent, or RetainTemporary.
Specifies the connection to the X server.
Specifies any resource associated with the client that you want to destroy or AllTemporary.
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.
