FID

InformationLevel

FID (2 bytes): This field MUST contain a valid FID returned from a previously successful SMB open command.

InformationLevel (2 bytes): This field contains an information level code, which determines the information contained in the response. The list of valid information level codes is specified in section 2.2.2.3.3. A client that has not negotiated long names support MUST request only SMB_INFO_STANDARD. If a client that has not negotiated long names support requests an InformationLevel other than SMB_INFO_STANDARD, the server MUST return a status of STATUS_INVALID_PARAMETER (ERRDOS/ERRinvalidparam).

Trans2_Data: The Trans2_Data field MUST be included if the Trans2_Parameters.InformationLevel field is set to SMB_INFO_QUERY_EAS_FROM_LIST; else, it MUST NOT be included.

 Trans2_Data
   {
   SMB_GEA_LIST GetExtendedAttributeList;
   }

GetExtendedAttributeList (variable): A list of extended attribute (EA) names. The server MUST return only those extended attributes that have an AttributeName matching one of the AttributeName values in the list.
