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> ] [ @ <integer> ] [ NONAME ] [CONSTANT] [DATA] ) *
51 Declares name1 as an exported symbol from the
52 DLL, with optional ordinal number <integer>
54 IMPORTS ( ( <internal-name> = <module-name> . <integer> )
55 | ( [ <internal-name> = ] <module-name> . <external-name> )) *
56 Declares that <external-name> or the exported function whoes ordinal number
57 is <integer> is to be imported from the file <module-name>. If
58 <internal-name> is specified then this is the name that the imported
59 function will be refered to in the body of the DLL.
62 Puts <string> into output .exp file in the .rdata section
64 [STACKSIZE|HEAPSIZE] <number-reserve> [ , <number-commit> ]
65 Generates --stack|--heap <number-reserve>,<number-commit>
66 in the output .drectve section. The linker will
67 see this and act upon it.
70 SECTIONS ( <sectionname> <attr>+ )*
71 <attr> = READ | WRITE | EXECUTE | SHARED
72 Generates --attr <sectionname> <attr> in the output
73 .drectve section. The linker will see this and act
77 A -export:<name> in a .drectve section in an input .o or .a
78 file to this program is equivalent to a EXPORTS <name>
83 The program generates output files with the prefix supplied
84 on the command line, or in the def file, or taken from the first
87 The .exp.s file contains the information necessary to export
88 the routines in the DLL. The .lib.s file contains the information
89 necessary to use the DLL's routines from a referencing program.

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

310 When IMPORT declarations are encountered in a .def file the
311 function import information is stored in a structure referenced by
312 the global variable IMPORT_LIST. The structure is a linked list
313 containing the names of the dll files each function is imported
314 from and a linked list of functions being imported from that dll
315 file. This roughly parallels the structure of the .idata section
316 in the PE object file.
318 The contents of .def file are interpreted from within the
319 process_def_file function. Every time an IMPORT declaration is
320 encountered, it is broken up into its component parts and passed to
