30 Specification 4.1" for more information.
32 A DLL contains an export table which contains the information
33 which the runtime loader needs to tie up references from a
36 The export table is generated by this program by reading
37 in a .DEF file or scanning the .a and .o files which will be in the
38 DLL. A .o file can contain information in special ".drectve" sections
39 with export information.
41 A DEF file contains any number of the following commands:
44 NAME <name> [ , <base> ]
45 The result is going to be <name>.EXE
47 LIBRARY <name> [ , <base> ]
48 The result is going to be <name>.DLL
50 EXPORTS ( ( ( <name1> [ = <name2> ] )
51 | ( <name1> = <module-name> . <external-name>))
52 [ @ <integer> ] [ NONAME ] [CONSTANT] [DATA] ) *
53 Declares name1 as an exported symbol from the
54 DLL, with optional ordinal number <integer>.
55 Or declares name1 as an alias (forward) of the function <external-name>
56 in the DLL <module-name>.
58 IMPORTS ( ( <internal-name> = <module-name> . <integer> )
59 | ( [ <internal-name> = ] <module-name> . <external-name> )) *
60 Declares that <external-name> or the exported function whoes ordinal number
61 is <integer> is to be imported from the file <module-name>. If
62 <internal-name> is specified then this is the name that the imported
63 function will be refered to in the body of the DLL.
66 Puts <string> into output .exp file in the .rdata section
68 [STACKSIZE|HEAPSIZE] <number-reserve> [ , <number-commit> ]
69 Generates --stack|--heap <number-reserve>,<number-commit>
70 in the output .drectve section. The linker will
71 see this and act upon it.
74 SECTIONS ( <sectionname> <attr>+ )*
75 <attr> = READ | WRITE | EXECUTE | SHARED
76 Generates --attr <sectionname> <attr> in the output
77 .drectve section. The linker will see this and act
81 A -export:<name> in a .drectve section in an input .o or .a
82 file to this program is equivalent to a EXPORTS <name>
87 The program generates output files with the prefix supplied
88 on the command line, or in the def file, or taken from the first
91 The .exp.s file contains the information necessary to export
92 the routines in the DLL. The .lib.s file contains the information
93 necessary to use the DLL's routines from a referencing program.

199 /* .idata section description
201 The .idata section is the import table. It is a collection of several
202 subsections used to keep the pieces for each dll together: .idata$[234567].
203 IE: Each dll's .idata$2's are catenated together, each .idata$3's, etc.
205 .idata$2 = Import Directory Table
206 = array of IMAGE_IMPORT_DESCRIPTOR's.
208 DWORD Import Lookup Table; - pointer to .idata$4
209 DWORD TimeDateStamp; - currently always 0
210 DWORD ForwarderChain; - currently always 0
211 DWORD Name; - pointer to dll's name
212 PIMAGE_THUNK_DATA FirstThunk; - pointer to .idata$5
214 .idata$3 = null terminating entry for .idata$2.
216 .idata$4 = Import Lookup Table
217 = array of array of pointers to hint name table.
218 There is one for each dll being imported from, and each dll's set is
219 terminated by a trailing NULL.
221 .idata$5 = Import Address Table
222 = array of array of pointers to hint name table.
223 There is one for each dll being imported from, and each dll's set is
224 terminated by a trailing NULL.
225 Initially, this table is identical to the Import Lookup Table. However,
226 at load time, the loader overwrites the entries with the address of the
229 .idata$6 = Hint Name Table
230 = Array of { short, asciz } entries, one for each imported function.
231 The `short' is the function's ordinal number.
233 .idata$7 = dll name (eg: "kernel32.dll"). (.idata$6 for ppc). */

312 When IMPORT declarations are encountered in a .def file the

314 the global variable IMPORT_LIST. The structure is a linked list
315 containing the names of the dll files each function is imported
316 from and a linked list of functions being imported from that dll
317 file. This roughly parallels the structure of the .idata section
318 in the PE object file.

1015 appended to it, the name of the function may be stored in internal
1016 or entry, and there may or may not be an ordinal value associated
1019 /* A note regarding the parse modes:
1020 In defparse.y we have to accept import declarations which follow

1026 Furthermore, the dll's name may or may not end with ".dll", which
1027 complicates the parsing a little. Normally the dll's name is
1028 passed to def_import() in the "module" parameter, but when it ends
1029 with ".dll" it gets passed in "module" sans ".dll" and that needs
1032 def_import gets five parameters:

1034 present, or NULL if not present.
1035 MODULE - the name of the dll, possibly sans extension (ie, '.dll').
1036 DLLEXT - the extension of the dll, if present, NULL if not present.
1037 ENTRY - the name of the function in the dll, if present, or NULL.
1038 ORD_VAL - the numerical tag of the function in the dll, if present,
