c9e38879 | 22 | /* This program allows you to build the files necessary to create |
252b5132 RH |
23 | DLLs to run on a system which understands PE format image files. |
24 | (eg, Windows NT) | |
25 | ||
26 | See "Peering Inside the PE: A Tour of the Win32 Portable Executable | |
27 | File Format", MSJ 1994, Volume 9 for more information. | |
28 | Also see "Microsoft Portable Executable and Common Object File Format, | |
29 | Specification 4.1" for more information. | |
30 | ||
31 | A DLL contains an export table which contains the information | |
32 | which the runtime loader needs to tie up references from a | |
33 | referencing program. | |
34 | ||
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. | |
39 | ||
40 | A DEF file contains any number of the following commands: | |
41 | ||
42 | ||
43 | NAME <name> [ , <base> ] | |
44 | The result is going to be <name>.EXE | |
45 | ||
46 | LIBRARY <name> [ , <base> ] | |
47 | The result is going to be <name>.DLL | |
48 | ||
04847a4d CF |
49 | EXPORTS ( ( ( <name1> [ = <name2> ] ) |
50 | | ( <name1> = <module-name> . <external-name>)) | |
7aa52b1f | 51 | [ @ <integer> ] [ NONAME ] [CONSTANT] [DATA] [PRIVATE] ) * |
252b5132 | 52 | Declares name1 as an exported symbol from the |
04847a4d CF |
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>. | |
252b5132 RH |
56 | |
57 | IMPORTS ( ( <internal-name> = <module-name> . <integer> ) | |
58 | | ( [ <internal-name> = ] <module-name> . <external-name> )) * | |
c7de9216 | 59 | Declares that <external-name> or the exported function whose ordinal number |
252b5132 RH |
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 | |
50c2245b | 62 | function will be refereed to in the body of the DLL. |
252b5132 RH |
63 | |
64 | DESCRIPTION <string> | |
65 | Puts <string> into output .exp file in the .rdata section | |
66 | ||
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. | |
71 | ||
72 | [CODE|DATA] <attr>+ | |
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 | |
77 | upon it. | |
78 | ||
79 | ||
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> | |
82 | in a .DEF file. | |
83 | ||
84 | ||
85 | ||
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 | |
88 | supplied argument. | |
89 | ||
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. | |
93 | ||

1244 | MODULE - the name of the dll, possibly sans extension (ie, '.dll'). | |
1245 | DLLEXT - the extension of the dll, if present, NULL if not present. | |
1246 | ENTRY - the name of the function in the dll, if present, or NULL. | |
1247 | ORD_VAL - the numerical tag of the function in the dll, if present, | |
1248 | or NULL. Exactly one of <entry> or <ord_val> must be | |
