24 DLLs to run on a system which understands PE format image files.
27 See "Peering Inside the PE: A Tour of the Win32 Portable Executable
28 File Format", MSJ 1994, Volume 9 for more information.
29 Also see "Microsoft Portable Executable and Common Object File Format,
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] [PRIVATE] ) *
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 whose 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 refereed 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). */
