This program allows you to build the files necessary to create
|
|
DLLs to run on a system which understands PE format image files.
|
|
(eg, Windows NT)
|
|
|
|
See "Peering Inside the PE: A Tour of the Win32 Portable Executable
|
|
File Format", MSJ 1994, Volume 9 for more information.
|
|
Also see "Microsoft Portable Executable and Common Object File Format,
|
|
Specification 4.1" for more information.
|
|
|
|
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> ] [ @ <integer> ] [ NONAME ] [CONSTANT] [DATA] ) *
|
|
Declares name1 as an exported symbol from the
|
|
DLL, with optional ordinal number <integer>
|
|
|
|
IMPORTS ( ( <internal-name> = <module-name> . <integer> )
|
|
| ( [ <internal-name> = ] <module-name> . <external-name> )) *
|
|
Declares that <external-name> or the exported function whoes 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 refered 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.
|
|
|
|
|

|

/* .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)

When IMPORT declarations are encountered in a .def file the

function import information is stored in a structure referenced by

the global variable IMPORT_LIST. The structure is a linked list

from and a linked list of functions being imported from that dll
|
|
file. This roughly parallels the structure of the .idata section
|
|
in the PE object file.
|
|
|
|
The contents of .def file are interpreted from within the
|
|
process_def_file function. Every time an IMPORT declaration is

def_import. IMPORT_LIST is initialized to NULL in function main. */

|
Furthermore, the dll's name may or may not end with ".dll", which
|
|
complicates the parsing a little. Normally the dll's name is
|
|
passed to def_import() in the "module" parameter, but when it ends
|
|
with ".dll" it gets passed in "module" sans ".dll" and that needs
|
|
to be reappended.
|
|
|
|
def_import gets five parameters:
|
|
APP_NAME - the name of the function in the application, if
|
|
present, or NULL if not present.
|
|
MODULE - the name of the dll, possibly sans extension (ie, '.dll').
|
|
DLLEXT - the extension of the dll, if present, NULL if not present.
|
|
ENTRY - the name of the function in the dll, if present, or NULL.
|
|
ORD_VAL - the numerical tag of the function in the dll, if present,
|
|
or NULL. Exactly one of <entry> or <ord_val> must be
|
|
present (i.e., not NULL). */
