It requires 26 the nlm/common.h file which contains the portions that are common to 27 both the internal and external representations. 28 29 Note that an NLM header consists of three parts: 30 31 (1) A fixed length header that has specific fields of known length, 32 at specific offsets in the file. 33 34 (2) A variable length header that has specific fields in a specific 35 order, but some fields may be variable length. 36 37 (3) A auxiliary header that has various optional fields in no specific 38 order. There is no way to identify the end of the auxiliary headers 39 except by finding a header without a recognized 'stamp'. 40 41 The exact format of the fixed length header unfortunately varies 42 from one NLM target to another, due to padding. Each target 43 defines the correct external format in a separate header file. */ 44 45 /* NLM Header. */ 46 47 /* The version header is one of the optional auxiliary headers and 48 follows the fixed length and variable length NLM headers. */ 49 50 typedef struct nlmNAME(external_version_header) 51 { 52 53 /* The header is recognized by "VeRsIoN#" in the stamp field. */ 54 char stamp[8]; 55 56 unsigned char majorVersion[NLM_TARGET_LONG_SIZE]; 57 58 unsigned char minorVersion[NLM_TARGET_LONG_SIZE]; 59 60 unsigned char revision[NLM_TARGET_LONG_SIZE]; 61 62 unsigned char year[NLM_TARGET_LONG_SIZE]; 63 64 unsigned char month[NLM_TARGET_LONG_SIZE]; 65 66 unsigned char day[NLM_TARGET_LONG_SIZE]; 67 68 } NlmNAME(External_Version_Header); 69 70 71 typedef struct nlmNAME(external_copyright_header) 72 { 73 74 /* The header is recognized by "CoPyRiGhT=" in the stamp field. */ 75 76 char stamp[10]; 77 78 unsigned char copyrightMessageLength[1]; 79 80 /* There is a variable length field here called 'copyrightMessage' 81 that is the length specified by copyrightMessageLength. */ 82 83 } NlmNAME(External_Copyright_Header); 84 85 86 typedef struct nlmNAME(external_extended_header) 87 { 88 89 /* The header is recognized by "MeSsAgEs" in the stamp field. */ 90 91 char stamp[8]; 92 93 unsigned char languageID[NLM_TARGET_LONG_SIZE]; 94 95 unsigned char messageFileOffset[NLM_TARGET_LONG_SIZE]; 96 97 unsigned char messageFileLength[NLM_TARGET_LONG_SIZE]; 98 99 unsigned char messageCount[NLM_TARGET_LONG_SIZE]; 100 101 unsigned char helpFileOffset[NLM_TARGET_LONG_SIZE]; 102 103 unsigned char helpFileLength[NLM_TARGET_LONG_SIZE]; 104 105 unsigned char RPCDataOffset[NLM_TARGET_LONG_SIZE]; 106 107 unsigned char RPCDataLength[NLM_TARGET_LONG_SIZE]; 108 109 unsigned char sharedCodeOffset[NLM_TARGET_LONG_SIZE]; 110 111 unsigned char sharedCodeLength[NLM_TARGET_LONG_SIZE]; 112 113 unsigned char sharedDataOffset[NLM_TARGET_LONG_SIZE]; 114 115 unsigned char sharedDataLength[NLM_TARGET_LONG_SIZE]; 116 117 unsigned char sharedRelocationFixupOffset[NLM_TARGET_LONG_SIZE]; 118 119 unsigned char sharedRelocationFixupCount[NLM_TARGET_LONG_SIZE]; 120 121 unsigned char sharedExternalReferenceOffset[NLM_TARGET_LONG_SIZE]; 122 123 unsigned char sharedExternalReferenceCount[NLM_TARGET_LONG_SIZE]; 124 125 unsigned char sharedPublicsOffset[NLM_TARGET_LONG_SIZE]; 126 127 unsigned char sharedPublicsCount[NLM_TARGET_LONG_SIZE]; 128 129 unsigned char sharedDebugRecordOffset[NLM_TARGET_LONG_SIZE]; 130 131 unsigned char sharedDebugRecordCount[NLM_TARGET_LONG_SIZE]; 132 133 unsigned char sharedInitializationOffset[NLM_TARGET_ADDRESS_SIZE]; 134 135 unsigned char SharedExitProcedureOffset[NLM_TARGET_ADDRESS_SIZE]; 136 137 unsigned char productID[NLM_TARGET_LONG_SIZE]; 138 139 unsigned char reserved0[NLM_TARGET_LONG_SIZE]; 140 141 unsigned char reserved1[NLM_TARGET_LONG_SIZE]; 142 143 unsigned char reserved2[NLM_TARGET_LONG_SIZE]; 144 145 unsigned char reserved3[NLM_TARGET_LONG_SIZE]; 146 147 unsigned char reserved4[NLM_TARGET_LONG_SIZE]; 148 149 unsigned char reserved5[NLM_TARGET_LONG_SIZE]; 150 151 } NlmNAME(External_Extended_Header); 152 153 154 typedef struct nlmNAME(external_custom_header) 155 { 156 157 /* The header is recognized by "CuStHeAd" in the stamp field. */ 158 char stamp[8]; 159 160 /* Length of this header. */ 161 unsigned char length[NLM_TARGET_LONG_SIZE]; 162 163 /* Offset to data. */ 164 unsigned char dataOffset[NLM_TARGET_LONG_SIZE]; 165 166 /* Length of data. */ 167 unsigned char dataLength[NLM_TARGET_LONG_SIZE]; 168 169 /* Stamp for this customer header--we recognize "CyGnUsEx". */ 170 char dataStamp[8]; 171 172 } NlmNAME(External_Custom_Header); 173
