I.E. it describes the in-file representation of NLM. It requires the nlm/common.h file which contains the portions that are common to both the internal and external representations. Note that an NLM header consists of three parts: (1) A fixed length header that has specific fields of known length, at specific offsets in the file. (2) A variable length header that has specific fields in a specific order, but some fields may be variable length. (3) A auxiliary header that has various optional fields in no specific order. There is no way to identify the end of the auxiliary headers except by finding a header without a recognized 'stamp'. The exact format of the fixed length header unfortunately varies from one NLM target to another, due to padding. Each target defines the correct external format in a separate header file. */ /* NLM Header */ /* The version header is one of the optional auxiliary headers and follows the fixed length and variable length NLM headers. */ typedef struct nlmNAME(external_version_header) { /* The header is recognized by "VeRsIoN#" in the stamp field. */ char stamp[8]; unsigned char majorVersion[NLM_TARGET_LONG_SIZE]; unsigned char minorVersion[NLM_TARGET_LONG_SIZE]; unsigned char revision[NLM_TARGET_LONG_SIZE]; unsigned char year[NLM_TARGET_LONG_SIZE]; unsigned char month[NLM_TARGET_LONG_SIZE]; unsigned char day[NLM_TARGET_LONG_SIZE]; } NlmNAME(External_Version_Header); typedef struct nlmNAME(external_copyright_header) { /* The header is recognized by "CoPyRiGhT=" in the stamp field. */ char stamp[10]; unsigned char copyrightMessageLength[1]; /* There is a variable length field here called 'copyrightMessage' that is the length specified by copyrightMessageLength. */ } NlmNAME(External_Copyright_Header); typedef struct nlmNAME(external_extended_header) { /* The header is recognized by "MeSsAgEs" in the stamp field. */ char stamp[8]; unsigned char languageID[NLM_TARGET_LONG_SIZE]; unsigned char messageFileOffset[NLM_TARGET_LONG_SIZE]; unsigned char messageFileLength[NLM_TARGET_LONG_SIZE]; unsigned char messageCount[NLM_TARGET_LONG_SIZE]; unsigned char helpFileOffset[NLM_TARGET_LONG_SIZE]; unsigned char helpFileLength[NLM_TARGET_LONG_SIZE]; unsigned char RPCDataOffset[NLM_TARGET_LONG_SIZE]; unsigned char RPCDataLength[NLM_TARGET_LONG_SIZE]; unsigned char sharedCodeOffset[NLM_TARGET_LONG_SIZE]; unsigned char sharedCodeLength[NLM_TARGET_LONG_SIZE]; unsigned char sharedDataOffset[NLM_TARGET_LONG_SIZE]; unsigned char sharedDataLength[NLM_TARGET_LONG_SIZE]; unsigned char sharedRelocationFixupOffset[NLM_TARGET_LONG_SIZE]; unsigned char sharedRelocationFixupCount[NLM_TARGET_LONG_SIZE]; unsigned char sharedExternalReferenceOffset[NLM_TARGET_LONG_SIZE]; unsigned char sharedExternalReferenceCount[NLM_TARGET_LONG_SIZE]; unsigned char sharedPublicsOffset[NLM_TARGET_LONG_SIZE]; unsigned char sharedPublicsCount[NLM_TARGET_LONG_SIZE]; unsigned char sharedDebugRecordOffset[NLM_TARGET_LONG_SIZE]; unsigned char sharedDebugRecordCount[NLM_TARGET_LONG_SIZE]; unsigned char sharedInitializationOffset[NLM_TARGET_ADDRESS_SIZE]; unsigned char SharedExitProcedureOffset[NLM_TARGET_ADDRESS_SIZE]; unsigned char productID[NLM_TARGET_LONG_SIZE]; unsigned char reserved0[NLM_TARGET_LONG_SIZE]; unsigned char reserved1[NLM_TARGET_LONG_SIZE]; unsigned char reserved2[NLM_TARGET_LONG_SIZE]; unsigned char reserved3[NLM_TARGET_LONG_SIZE]; unsigned char reserved4[NLM_TARGET_LONG_SIZE]; unsigned char reserved5[NLM_TARGET_LONG_SIZE]; } NlmNAME(External_Extended_Header); typedef struct nlmNAME(external_custom_header) { /* The header is recognized by "CuStHeAd" in the stamp field. */ char stamp[8]; /* Length of this header. */ unsigned char length[NLM_TARGET_LONG_SIZE]; /* Offset to data. */ unsigned char dataOffset[NLM_TARGET_LONG_SIZE]; /* Length of data. */ unsigned char dataLength[NLM_TARGET_LONG_SIZE]; /* Stamp for this customer header--we recognize "CyGnUsEx". */ char dataStamp[8]; } NlmNAME(External_Custom_Header);
