27 * SMB: process_exit
28 *
29 * This command informs the server that a client process has terminated.
30 * The server must close all files opened by Pid in the SMB header. This
31 * must automatically release all locks the process holds.
32 *
33 * Client Request Description
34 * ================================== =================================
35 *
36 * UCHAR WordCount; Count of parameter words = 0
37 * USHORT ByteCount; Count of data bytes = 0
38 *
39 * Server Response Description
40 * ================================== =================================
41 *
42 * UCHAR WordCount; Count of parameter words = 0
43 * USHORT ByteCount; Count of data bytes = 0
44 *
45 * This SMB should not generate any errors from the server, unless the
46 * server is a user mode server and Uid in the SMB header is invalid.
47 *
48 * Clients are not required to send this SMB, they can do all cleanup
49 * necessary by sending close SMBs to the server to release resources. In
50 * fact, clients who have negotiated LANMAN 1.0 and later probably do not
51 * send this message at all.
