44 handle_write_invis [-c char] [-o offset] [-l length] [-s sid] handle
47 'char' is the character to use as a repeated pattern ('X' is the default),
48 'offset' is the offset of the start of the write (0 is the default),
49 'length' is the length of the write in bytes (1 is the default),
50 'sid' is the session ID whose events you you are interested in.
51 'handle' is the ascii representation of the file's handle.
52 You can use the test tool path_to_handle to get this.
54 DM_WRITE_SYNC is is not supported.
