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

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