Every major data structure in the file system is assigned a node 13 type code that is. This code is the first CSHORT in the structure and is 14 followed by a CSHORT containing the size, in bytes, of the structure. 15 16 17 --*/ 18 19 #ifndef _CDNODETYPE_ 20 #define _CDNODETYPE_ 21 22 typedef USHORT NODE_TYPE_CODE; 23 typedef NODE_TYPE_CODE *PNODE_TYPE_CODE; 24 25 #define NTC_UNDEFINED ((NODE_TYPE_CODE)0x0000) 26 27 #define CDFS_NTC_DATA_HEADER ((NODE_TYPE_CODE)0x0301) 28 #define CDFS_NTC_VCB ((NODE_TYPE_CODE)0x0302) 29 #define CDFS_NTC_FCB_PATH_TABLE ((NODE_TYPE_CODE)0x0303) 30 #define CDFS_NTC_FCB_INDEX ((NODE_TYPE_CODE)0x0304) 31 #define CDFS_NTC_FCB_DATA ((NODE_TYPE_CODE)0x0305) 32 #define CDFS_NTC_FCB_NONPAGED ((NODE_TYPE_CODE)0x0306) 33 #define CDFS_NTC_CCB ((NODE_TYPE_CODE)0x0307) 34 #define CDFS_NTC_IRP_CONTEXT ((NODE_TYPE_CODE)0x0308) 35 #define CDFS_NTC_IRP_CONTEXT_LITE ((NODE_TYPE_CODE)0x0309) 36 37 typedef CSHORT NODE_BYTE_SIZE; 38 39 // 40 // So all records start with 41 // 42 // typedef struct _RECORD_NAME { 43 // NODE_TYPE_CODE NodeTypeCode; 44 // NODE_BYTE_SIZE NodeByteSize; 45 // : 46 // } RECORD_NAME; 47 // typedef RECORD_NAME *PRECORD_NAME; 48 // 49 50 #ifndef NodeType 51 #define NodeType(P) ((P) != NULL ?
