* This module provides functions for TRANS2_FIND_FIRST2 and
* TRANS2_FIND_NEXT2 requests. The requests allow the client to search
* for the file(s) which match the file specification. The search is
* started with TRANS2_FIND_FIRST2 and can be continued if necessary with
* TRANS2_FIND_NEXT2. There are numerous levels of information which may be
* obtained for the returned files, the desired level is specified in the
* InformationLevel field of the requests.
*
* InformationLevel Name Value
* ================================= ================
*
* SMB_INFO_STANDARD 1
* SMB_INFO_QUERY_EA_SIZE 2
* SMB_INFO_QUERY_EAS_FROM_LIST 3
* SMB_FIND_FILE_DIRECTORY_INFO 0x101
* SMB_FIND_FILE_FULL_DIRECTORY_INFO 0x102
* SMB_FIND_FILE_NAMES_INFO 0x103
* SMB_FIND_FILE_BOTH_DIRECTORY_INFO 0x104
* SMB_FIND_FILE_ID_FULL_DIRECTORY_INFO 0x105
* SMB_FIND_FILE_ID_BOTH_DIRECTORY_INFO 0x106
*
* The following sections detail the data returned for each
* InformationLevel. The requested information is placed in the Data
* portion of the transaction response. Note: a client which does not
* support long names can only request SMB_INFO_STANDARD.
*
* A four-byte resume key precedes each data item (described below) if bit
* 2 in the Flags field is set, i.e. if the request indicates the server
* should return resume keys. Note: it is not always the case. If the
* data item already includes the resume key, the resume key should not be
* added again.
*
