c9e38879 | 23 | /* This program allows you to build the files necessary to create |
252b5132 RH |
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 | ||
04847a4d CF |
50 | EXPORTS ( ( ( <name1> [ = <name2> ] ) |
51 | | ( <name1> = <module-name> . <external-name>)) | |
7aa52b1f | 52 | [ @ <integer> ] [ NONAME ] [CONSTANT] [DATA] [PRIVATE] ) * |
252b5132 | 53 | Declares name1 as an exported symbol from the |
04847a4d CF |
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>. | |
252b5132 RH |
57 | |
58 | IMPORTS ( ( <internal-name> = <module-name> . <integer> ) | |
59 | | ( [ <internal-name> = ] <module-name> . <external-name> )) * | |
c7de9216 | 60 | Declares that <external-name> or the exported function whose ordinal number |
252b5132 RH |
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 | |
50c2245b | 63 | function will be refereed to in the body of the DLL. |
252b5132 RH |
64 | |
65 | DESCRIPTION <string> | |
66 | Puts <string> into output .exp file in the .rdata section | |
67 | ||
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. | |
72 | ||
73 | [CODE|DATA] <attr>+ | |
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 | |
78 | upon it. | |
79 | ||
80 | ||
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> | |
83 | in a .DEF file. | |
84 | ||
85 | ||
86 | ||
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 | |
89 | supplied argument. | |
90 | ||
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. | |
94 | ||

109 | { | |

111 | } | |

1102 | DLLEXT - the extension of the dll, if present, NULL if not present. | |
1103 | ENTRY - the name of the function in the dll, if present, or NULL. | |
1104 | ORD_VAL - the numerical tag of the function in the dll, if present, | |
1105 | or NULL. Exactly one of <entry> or <ord_val> must be | |
