|

Winedump can be used for different usages:

- generating default source files (.spec, .c...) for using a native DLL in Wine

- demangling MSVC C++ symbol names

- dumping the 'PE' files contents

Sym mode: Demangling
|
||||
--------------------
|
||||
|

If you need to demangle a single C++ symbol, you can use the demangling mode
|
||||
of winedump. This is useful for testing the demangler or implementing
|
||||
C++ functions in partially implemented wine DLLS. As an example:
|
||||
|
||||
winedump sym "??3@YAXPAX@Z"

||||
|
||||
Gives:
|
||||
|

Dump Mode: Dumping a PE file
|
||||
----------------------------
|
||||
|
||||
Another use for this tool is to diplay information about a 32bit DLL or PE
|
||||
format image file. When used in this way winedump functions similarly to tools
|
||||
such as pedump provided by many Win32 compiler vendors.
|
||||
|
||||
Usage:
|
||||
winedump dump <dllname.dll> [switches]

||||
|
||||
dump mode switches:
|
||||
-h Display this help message
|
||||
-C Turns on symbol demangling
|
||||
-f Dump file header information
|
||||
-j dir_name Dump only the contents of directory dir_name (import, export, debug)
|

-x Dump everything

|

Dump Mode: Options
|

------------------
|
||||
|
||||
OPTION: -x Dump everything
|
||||
|
||||
This command prints all available information about the file. You may wish to
|
||||
pipe the output through more/less or into a file, since a lot of output will
|
||||
be produced.
|
||||
|
||||
If you are only interested in a subset of the available information, you can
|
||||
use one of the following switches:
|
||||
|
||||
OPTION: -f Dump file header information-x Dump everything
|
||||
|
||||
This option dumps only the standard PE header structures, along with the COFF
|
||||
sections available in the file.
|
||||
|
||||
OPTION: -j dir_name Dump directory dir_name (import, export, debug)
|
||||
|
||||
To dump only a given directory, specify them using this option. Currently only
|
||||
the import, export and debug directories are implemented.

Dumping

|

Another tool might be helpful for digging into a 32bit DLL (and any PE image file):
|
||||
pedump.
|
||||
|
||||
Usage:
|
||||
winedump [-h | sym <sym> | spec <dll> | dump <dll> ] [switches]
|
||||
|
||||
winedump switches:
|
||||
-h Display this help message
|
||||
-d <dll> Use dll for input file and generate implementation code
|
||||
-C Turns on symbol demangling
|
||||
-f Dumps file header information
|
||||
-j dir_name Dumps only the content of directory dir_name (import, export, debug)
|
||||
-x Dumps everything
|
||||
|
||||
The basic usage, to look at everything in a file is:
|
||||
winedump dump mydll.dll -x
|
||||
|
||||
It'll print any available information on the file. This information can be splitted
|
||||
into sub-categories:
|
||||
- file headers (request by -f or -x) are made of the standard PE header structures,
|
||||
plus the COFF sections
|
||||
- directories: you can print them one after the other using the -j switch.
|
||||
Currently, only the import, export and debug directories are implemented.
|
||||
- -x displays the file headers and any available directory.
