32 | A DLL contains an export table which contains the information |
33 | which the runtime loader needs to tie up references from a | |
c027e8b0 | 34 | referencing program. |
765e60a9 SC |
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 | |
199f5217 | 38 | DLL. A .o file can contain information in special ".drectve" sections |
c027e8b0 | 39 | with export information. |
765e60a9 SC |
40 | |
41 | A DEF file contains any number of the following commands: | |
42 | ||
43 | ||
c027e8b0 | 44 | NAME <name> [ , <base> ] |
6f2d3212 | 45 | The result is going to be <name>.EXE |
765e60a9 | 46 | |
c027e8b0 | 47 | LIBRARY <name> [ , <base> ] |
6f2d3212 | 48 | The result is going to be <name>.DLL |
765e60a9 | 49 | |
c336631b | 50 | EXPORTS ( <name1> [ = <name2> ] [ @ <integer> ] [ NONAME ] [CONSTANT] [DATA] ) * |
6f2d3212 SC |
51 | Declares name1 as an exported symbol from the |
52 | DLL, with optional ordinal number <integer> | |
765e60a9 | 53 | |
061ed861 NC |
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. | |
765e60a9 SC |
60 | |
61 | DESCRIPTION <string> | |
6f2d3212 | 62 | Puts <string> into output .exp file in the .rdata section |
765e60a9 SC |
63 | |
64 | [STACKSIZE|HEAPSIZE] <number-reserve> [ , <number-commit> ] | |
6f2d3212 | 65 | Generates --stack|--heap <number-reserve>,<number-commit> |
199f5217 | 66 | in the output .drectve section. The linker will |
6f2d3212 | 67 | see this and act upon it. |

70 | SECTIONS ( <sectionname> <attr>+ )* | |
6f2d3212 SC |
71 | <attr> = READ | WRITE | EXECUTE | SHARED |
72 | Generates --attr <sectionname> <attr> in the output | |
199f5217 | 73 | .drectve section. The linker will see this and act |
6f2d3212 | 74 | upon it. |
765e60a9 SC |
75 | |
76 | ||
199f5217 | 77 | A -export:<name> in a .drectve section in an input .o or .a |
765e60a9 SC |
78 | file to this program is equivalent to a EXPORTS <name> |
79 | in a .DEF file. | |
80 | ||
81 | ||
82 | ||
6f2d3212 | 83 | The program generates output files with the prefix supplied |
c027e8b0 | 84 | on the command line, or in the def file, or taken from the first |
6f2d3212 | 85 | supplied argument. |
765e60a9 | 86 | |
6f2d3212 SC |
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. | |

a4e5fd18 BM |
882 | <func_name_in_app> = <dll_name>.<func_name_in_dll> |

887 | complicates the parsing a little. Normally the dll's name is | |
888 | passed to def_import() in the "module" parameter, but when it ends | |
889 | with ".dll" it gets passed in "module" sans ".dll" and that needs | |
890 | to be reappended. | |

892 | def_import gets five parameters: | |
893 | APP_NAME - the name of the function in the application, if | |
a4e5fd18 | 894 | present, or NULL if not present. |
c027e8b0 ILT |
895 | MODULE - the name of the dll, possibly sans extension (ie, '.dll'). |
896 | DLLEXT - the extension of the dll, if present, NULL if not present. | |
897 | ENTRY - the name of the function in the dll, if present, or NULL. | |
898 | ORD_VAL - the numerical tag of the function in the dll, if present, | |
899 | or NULL. Exactly one of <entry> or <ord_val> must be | |
