23 | This program allows you to build the files necessary to create | |
24 | DLLs to run on a system which understands PE format image files. | |
25 | (eg, Windows NT) | |
26 | ||
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. | |
31 | ||
32 | A DLL contains an export table which contains the information | |
33 | which the runtime loader needs to tie up references from a | |
34 | referencing program. | |
35 | ||
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. | |
40 | ||
41 | A DEF file contains any number of the following commands: | |
42 | ||
43 | ||
44 | NAME <name> [ , <base> ] | |
45 | The result is going to be <name>.EXE | |
46 | ||
47 | LIBRARY <name> [ , <base> ] | |
48 | The result is going to be <name>.DLL | |
49 | ||
50 | EXPORTS ( <name1> [ = <name2> ] [ @ <integer> ] [ NONAME ] [CONSTANT] [DATA] ) * | |
51 | Declares name1 as an exported symbol from the | |
52 | DLL, with optional ordinal number <integer> | |
53 | ||
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. | |
60 | ||
61 | DESCRIPTION <string> | |
62 | Puts <string> into output .exp file in the .rdata section | |
63 | ||
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. | |
68 | ||
69 | [CODE|DATA] <attr>+ | |
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 | |
74 | upon it. | |
75 | ||
76 | ||
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> | |
79 | in a .DEF file. | |
80 | ||
81 | ||
82 | ||
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 | |
85 | supplied argument. | |
86 | ||
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. | |
90 | ||
91 | ||
92 | ||

94 | ||
95 | file1.c: | |
96 | asm (".section .drectve"); | |
97 | asm (".ascii \"-export:adef\""); | |
98 | ||

104 | void bdef (char * s) | |
105 | { | |
106 | printf ("hello from the dll and the other entry point %s\n", s); | |
107 | } | |
108 | ||
109 | file2.c: | |
110 | asm (".section .drectve"); | |
111 | asm (".ascii \"-export:cdef\""); | |
112 | asm (".ascii \"-export:ddef\""); | |
113 | ||
114 | void cdef (char * s) | |

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. | |
201 | ||

209 | PIMAGE_THUNK_DATA FirstThunk; - pointer to .idata$5 | |
210 | ||
211 | .idata$3 = null terminating entry for .idata$2. | |
212 | ||
213 | .idata$4 = Import Lookup Table | |
214 | = array of array of pointers to hint name table. | |

222 | Initially, this table is identical to the Import Lookup Table. However, | |

1064 | DLLEXT - the extension of the dll, if present, NULL if not present. | |
1065 | ENTRY - the name of the function in the dll, if present, or NULL. | |
1066 | ORD_VAL - the numerical tag of the function in the dll, if present, | |
1067 | or NULL. Exactly one of <entry> or <ord_val> must be | |
