Help mode¶

No options are used. The program prints the help info and then exits.

Dump mode¶

file

Dumps the contents of file. Various file formats are supported (PE, NE, LE, Minidumps, .lnk).

-C

Turns on symbol demangling.

-f

Dumps file header information. This option dumps only the standard PE header structures, along with the COFF sections available in the file.

-j dir_name

Dumps only the content of directory dir_name, for files which header points to directories. For PE files, the import, export, debug, resource, tls, loadcfg, clr, reloc and except directories, as well as the apiset section, are implemented. For NE files, the export and resource directories are implemented.

-x

Dumps everything. This command prints all available information (including all available directories - see -j option) 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.

-G

Dumps contents of debug section if any (for now, only stabs information is supported).

Spec mode¶

dll

Use dll for input file and generate implementation code.

-I dir

Look for prototypes in dir (implies -c). In the case of Windows DLLs, this could be either the standard include directory from your compiler, or a SDK include directory. If you have a text document with prototypes (such as documentation) that can be used also, however you may need to delete some non-code lines to ensure that prototypes are parsed correctly. The dir argument can also be a file specification (e.g. include/*). If it contains wildcards you must quote it to prevent the shell from expanding it. If you have no prototypes, specify /dev/null as dir. winedump may still be able to generate some working stub code for you.

-c

Generate skeleton code (requires -I). This option tells winedump to create function stubs for each function in the DLL. As winedump reads each exported symbol from the source DLL, it first tries to demangle the name. If the name is a C++ symbol, the arguments, class and return value are all encoded into the symbol name. Winedump converts this information into a C function prototype. If this fails, the file(s) specified in the -I argument are scanned for a function prototype. If one is found it is used for the next step of the process, code generation.

-t

TRACE arguments (implies -c). This option produces the same code as -c, except that arguments are printed out when the function is called. Structs that are passed by value are printed as "struct", and functions that take variable argument lists print "...".

-f dll

Forward calls to dll (implies -t). This is the most complicated level of code generation. The same code is generated as -t, however support is added for forwarding calls to another DLL. The DLL to forward to is given as dll.

-D

Generate documentation. By default, winedump generates a standard comment at the header of each function it generates. Passing this option makes winedump output a full header template for standard Wine documentation, listing the parameters and return value of the function.

-o name

Set the output dll name (default: dll). By default, if winedump is run on DLL foo, it creates files foo.spec, foo_main.c etc, and prefixes any functions generated with FOO_. If -o bar is given, these will become bar.spec, bar_main.c and BAR_ respectively. This option is mostly useful when generating a forwarding DLL.

-C

Assume __cdecl calls (default: __stdcall). If winebuild cannot determine the calling convention, __stdcall is used by default, unless this option has been given. Unless -q is given, a warning will be printed for every function that winedump determines the calling convention for and which does not match the assumed calling convention.

-s num

Start prototype search after symbol num.

-e num

End prototype search after symbol num. By passing the -s or -e options you can have winedump try to generate code for only some functions in your DLL. This may be used to generate a single function, for example, if you wanted to add functionality to an existing DLL.

-S symfile

Search only prototype names found in symfile. If you want to only generate code for a subset of exported functions from your source DLL, you can use this option to provide a text file containing the names of the symbols to extract, one per line. Only the symbols present in this file will be used in your output DLL.

-q

Don't show progress (quiet). No output is printed unless a fatal error is encountered.

-v

Show lots of detail while working (verbose). There are 3 levels of output while winedump is running. The default level, when neither -q or -v are given, prints the number of exported functions found in the dll, followed by the name of each function as it is processed, and a status indication of whether it was processed OK. With -v given, a lot of information is dumped while winedump works: this is intended to help debug any problems.

Sym mode¶

sym

Demangles C++ symbol sym and then exits.
