AuKillClient.3x man page
AuKillClient - destroy a client or its remaining resources
void AuKillClient(server, resource, status)
AuStatus *status; /* RETURN */
Specifies the connection to the audio server.
Specifies the resource associated with the client to be destroyed or the constant AuCloseDownDestroy.
If non-NULL, flush the output buffer and return the status from the server.
AuKillClient forces a close-down of the client that created resource. If the client has already terminated in either AuCloseDownRetainPermanent or AuCloseDownRetainTemporary mode, all of the client's resources are destroyed. If resource is AuCloseDownDestroy, the resources of all clients that have terminated in AuCloseDownRetainTemporary are destroyed.
