21 | /* | |
22 | This program allows you to build the files necessary to create | |
23 | DLLs to run on a system which understands PE format image files. | |
24 | (eg, Windows NT) | |
25 | ||
26 | A DLL contains an export table which contains the information | |
27 | which the runtime loader needs to tie up references from a | |
28 | referencing program. | |
29 | ||
30 | The export table is generated by this program by reading | |
31 | in a .DEF file or scanning the .a and .o files which will be in the | |
32 | DLL. A .o file can contain information in special ".drective" sections | |
33 | with export information. | |
34 | ||
35 | A DEF file contains any number of the following commands: | |
36 | ||
37 | ||
38 | NAME <name> [ , <base> ] | |
6f2d3212 | 39 | The result is going to be <name>.EXE |
765e60a9 SC |
40 | |
41 | LIBRARY <name> [ , <base> ] | |
6f2d3212 | 42 | The result is going to be <name>.DLL |
765e60a9 SC |
43 | |
44 | EXPORTS ( <name1> [ = <name2> ] [ @ <integer> ] [ NONAME ] [CONSTANT] ) * | |
6f2d3212 SC |
45 | Declares name1 as an exported symbol from the |
46 | DLL, with optional ordinal number <integer> | |
765e60a9 SC |
47 | |
48 | IMPORTS ( [ <name> = ] <name> . <name> ) * | |
6f2d3212 | 49 | Ignored for compatibility |
765e60a9 SC |
50 | |
51 | DESCRIPTION <string> | |
6f2d3212 | 52 | Puts <string> into output .exp file in the .rdata section |
765e60a9 SC |
53 | |
54 | [STACKSIZE|HEAPSIZE] <number-reserve> [ , <number-commit> ] | |
6f2d3212 SC |
55 | Generates --stack|--heap <number-reserve>,<number-commit> |
56 | in the output .drective section. The linker will | |
57 | see this and act upon it. | |
765e60a9 SC |
58 | |
59 | [CODE|DATA] <attr>+ | |
60 | SECTIONS ( <sectionname> <attr>+ )* | |
6f2d3212 SC |
61 | <attr> = READ | WRITE | EXECUTE | SHARED |
62 | Generates --attr <sectionname> <attr> in the output | |
63 | .drective section. The linker will see this and act | |
64 | upon it. | |
765e60a9 SC |
65 | |
66 | ||
67 | A -export:<name> in a .drective section in an input .o or .a | |
68 | file to this program is equivalent to a EXPORTS <name> | |
69 | in a .DEF file. | |
70 | ||
71 | ||
72 | ||
6f2d3212 SC |
73 | The program generates output files with the prefix supplied |
74 | on the command line, or in the def file, or taken from the first | |
75 | supplied argument. | |
765e60a9 | 76 | |
6f2d3212 | 77 | The output files are <prefix>-exp.s and <prefix>-lib.s |
765e60a9 | 78 | |
6f2d3212 SC |
79 | The .exp.s file contains the information necessary to export |
80 | the routines in the DLL. The .lib.s file contains the information | |
81 | necessary to use the DLL's routines from a referencing program. | |
765e60a9 SC |
