| /* This program allows you to build the files necessary to create |

| |
| A DLL contains an export table which contains the information |
| which the runtime loader needs to tie up references from a |
| referencing program. |
| |
| The export table is generated by this program by reading |
| in a .DEF file or scanning the .a and .o files which will be in the |
| DLL. A .o file can contain information in special ".drectve" sections |
| with export information. |
| |
| A DEF file contains any number of the following commands: |
| |
| |
| NAME <name> [ , <base> ] |
| The result is going to be <name>.EXE |
| |
| LIBRARY <name> [ , <base> ] |
| The result is going to be <name>.DLL |
| |
| EXPORTS ( ( ( <name1> [ = <name2> ] ) |
| | ( <name1> = <module-name> . <external-name>)) |
| [ @ <integer> ] [ NONAME ] [CONSTANT] [DATA] [PRIVATE] ) * |
| Declares name1 as an exported symbol from the |
| DLL, with optional ordinal number <integer>. |
| Or declares name1 as an alias (forward) of the function <external-name> |
| in the DLL <module-name>. |
| |
| IMPORTS ( ( <internal-name> = <module-name> . <integer> ) |
| | ( [ <internal-name> = ] <module-name> . <external-name> )) * |
| Declares that <external-name> or the exported function whose ordinal number |
| is <integer> is to be imported from the file <module-name>. If |
| <internal-name> is specified then this is the name that the imported |
| function will be refereed to in the body of the DLL. |
| |
| DESCRIPTION <string> |
| Puts <string> into output .exp file in the .rdata section |
| |
| [STACKSIZE|HEAPSIZE] <number-reserve> [ , <number-commit> ] |
| Generates --stack|--heap <number-reserve>,<number-commit> |
| in the output .drectve section. The linker will |
| see this and act upon it. |
| |
| [CODE|DATA] <attr>+ |
| SECTIONS ( <sectionname> <attr>+ )* |
| <attr> = READ | WRITE | EXECUTE | SHARED |
| Generates --attr <sectionname> <attr> in the output |
| .drectve section. The linker will see this and act |
| upon it. |
| |
| |
| A -export:<name> in a .drectve section in an input .o or .a |
| file to this program is equivalent to a EXPORTS <name> |
| in a .DEF file. |
| |
| |
| |
| The program generates output files with the prefix supplied |
| on the command line, or in the def file, or taken from the first |
| supplied argument. |
| |
| The .exp.s file contains the information necessary to export |
| the routines in the DLL. The .lib.s file contains the information |
| necessary to use the DLL's routines from a referencing program. |
| |
| |
| |
| Example: |
| |
| file1.c: |
| asm (".section .drectve"); |
| asm (".ascii \"-export:adef\""); |
| |
| void adef (char * s) |
| { |
| printf ("hello from the dll %s\n", s); |
| } |
| |
| void bdef (char * s) |
| { |
| printf ("hello from the dll and the other entry point %s\n", s); |
| } |
| |
| file2.c: |
| asm (".section .drectve"); |
| asm (".ascii \"-export:cdef\""); |
| asm (".ascii \"-export:ddef\""); |
| |
| void cdef (char * s) |
| { |
| printf ("hello from the dll %s\n", s); |
| } |
| |
| void ddef (char * s) |
| { |
| printf ("hello from the dll and the other entry point %s\n", s); |
| } |
| |
| int printf (void) |
| { |
| return 9; |
| } |
| |
| themain.c: |
| int main (void) |
| { |
| cdef (); |
| return 0; |
| } |
| |
| thedll.def |
| |
| LIBRARY thedll |

| /* .idata section description |
| |
| The .idata section is the import table. It is a collection of several |
| subsections used to keep the pieces for each dll together: .idata$[234567]. |
| IE: Each dll's .idata$2's are catenated together, each .idata$3's, etc. |
| |
| .idata$2 = Import Directory Table |
| = array of IMAGE_IMPORT_DESCRIPTOR's. |
| |
| DWORD Import Lookup Table; - pointer to .idata$4 |
| DWORD TimeDateStamp; - currently always 0 |
| DWORD ForwarderChain; - currently always 0 |
| DWORD Name; - pointer to dll's name |
| PIMAGE_THUNK_DATA FirstThunk; - pointer to .idata$5 |
| |
| .idata$3 = null terminating entry for .idata$2. |
| |
| .idata$4 = Import Lookup Table |
| = array of array of pointers to hint name table. |
| There is one for each dll being imported from, and each dll's set is |
| terminated by a trailing NULL. |
| |
| .idata$5 = Import Address Table |
| = array of array of pointers to hint name table. |
| There is one for each dll being imported from, and each dll's set is |
| terminated by a trailing NULL. |
| Initially, this table is identical to the Import Lookup Table. However, |
| at load time, the loader overwrites the entries with the address of the |
| function. |
| |
| .idata$6 = Hint Name Table |
| = Array of { short, asciz } entries, one for each imported function. |
| The `short' is the function's ordinal number. |
| |
| .idata$7 = dll name (eg: "kernel32.dll"). (.idata$6 for ppc). */ |
