|
||
|
||
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.
|
||

||

/* .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.

complicates the parsing a little. Normally the dll's name is

with ".dll" it gets passed in "module" sans ".dll" and that needs

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). */
