To run dumpbin, use the following syntax:

DUMPBIN [options] files...

Specify one or more binary files and any options required to control information. Dumpbin displays the information to the standard output. You can redirect the output to a file, or use the/out option to specify the file name for the output.

When dumpbin is run on the file but no option is specified, dumpbin displays/summary output.

When you type a commanddumpbinHowever, when there is no other command line input, dumpbin displays usage statements that summarize its options.

Dumpbin Option

/ALL

This option displays all available information except code disassembly. Use/disasm to display disassembly. You can use/rawdata: None together with/all to omit the original binary details of the file.

Only the/headers dumpbin option can be used for files generated by the/GL compiler option.

/ARCHIVEMEMBERS

This option displays the minimum information about database Member objects.

Only the/headers dumpbin option can be used for files generated by the/GL compiler option.

/CLRHEADER file

Here:

File

Image files generated by/CLR.

Remarks

Clrheader displays information about. Net headers used in any hosting program. The output shows the. NET header and the position and size of each section (in bytes ).

File Format spec.doc describes the information in the. NET header. Install file format spec.doc in the tools developers Guide directory.

Only the/headers dumpbin option can be used for files generated by the/GL compiler option.

/DIRECTIVES

This option dumps the. ctictive section generated by the compiler in the image.

Only the/headers dumpbin option can be used for files generated by the/GL compiler option.

/DEPENDENTS

The name of the DLL from which the dump image is imported. Do not dump the imported function name.

Only the/headers dumpbin option can be used for files generated by the/GL compiler option.

/DISASM

This option displays the disassembly of the code segment. If it appears in a file, it uses a symbol.

Only the/headers dumpbin option can be used for files generated by the/GL compiler option.

/EXPORTS

This option displays all definitions exported from an executable file or DLL.

Only the/headers dumpbin option can be used for files generated by the/GL compiler option.

/FPO

This option displays frame Pointer Optimization (FPO) records.

Only the/headers dumpbin option can be used for files generated by the/GL compiler option.

/HEADERS

This option displays the file header and the header of each section. The header of each member object is displayed when used in the database.

Only the/headers dumpbin option can be used for files generated by the/GL compiler option.

/IMPORTS[:file]

This option displays the DLL list imported to an executable file or DLL (static link and delayed loading) and the various imports of each of the above DLL.

OptionalFileThe specification allows you to specify to display only the import of a DLL. For example:

dumpbin /IMPORTS:msvcrt.dll

The output displayed by this option is similar to the/exports output.

Only the/headers dumpbin option can be used for files generated by the/GL compiler option.

/LINENUMBERS

This option displays the coff row number. If the object file is compiled in a program database (/Zi), C7 compatible (/z7), or only by row number (/ZD), it contains the row number. If the executable file or DLL is linked to the generated debugging information (/debug), it contains the coff line number.

Only the/headers dumpbin option can be used for files generated by the/GL compiler option.

/LINKERMEMBER[:{1|2}]

This option displays the public symbols defined in the library. Specify parameter 1 to display the symbols and Their offsets in object order. Specify parameter 2 to display the object offset and index number, and then list these symbols and the object index of each symbol in alphabetical order. To obtain both outputs, specify/linkermember without the numeric parameter.

Only the/headers dumpbin option can be used for files generated by the/GL compiler option.

/LOADCONFIG

This option dumps the image_load_config_directory structure, which is an optional structure that is used by the Windows NT loader and defined in winnt. h.

Only the/headers dumpbin option can be used for files generated by the/GL compiler option.

/OUT:filename

This option specifies the outputFilename. By default, dumpbin displays the information to the standard output.

Only the/headers dumpbin option can be used for files generated by the/GL compiler option.

/PDBPATH[:VERBOSE] filename

Here:

Filename

Find the. dll or. EXE file name that matches the. PDB file.

Verbose (optional)

The report has tried to locate all directories in the. PDB file.

Remarks

/Pdbpath searches for computers in the same path as the debugger to search for. PDB files, and reports which. PDB files (if any) andFilenameCorresponds to the file specified in.

You may encounter problems when using the Visual Studio debugger because the debugger uses the. PDB file for different versions of the debug file.

/Pdbpath searches for the. PDB file in the following path:

• Check the location where executable files reside.
• Check the location of the PDB written to the executable file. This is usually the position when the image is linked.
• Check the search path configured in Visual Studio IDE.
• Check the path in the environment variables _ nt_symbol_path and _ nt_alt_symbol_path.
• Check in the Windows directory.

/PDATA

It is only used for the RISC processor.

This option dumps an exception table (. pdata) from an image or object ).

Only the/headers dumpbin option can be used for files generated by the/GL compiler option.

/RAWDATA[:{1|2|4|8|NONE[,number]]

This option displays the original content of each section in the file. The parameter control display format is as follows:

Parameters	Result
1	Default value. The content is displayed in hexadecimal bytes. If the content has a printed representation, it is also displayed as ASCII characters.
2	The content is displayed as a hexadecimal 2-byte value.
4	The content is displayed as a hexadecimal 4-byte value.
8	The content is displayed as the hexadecimal 8-byte value.
None	Undisplay raw data. This parameter is useful for controlling/all output.
Number	The displayed row is set to haveNumber.

Only the/headers dumpbin option can be used for files generated by the/GL compiler option.

/RELOCATIONS

This option displays any relocation of an object or image.

Only the/headers dumpbin option can be used for files generated by the/GL compiler option.

/SECTION:section

This option limitsSectionThe output of related information.

Only the/headers dumpbin option can be used for files generated by the/GL compiler option.

/SUMMARY

This option displays the minimum information (including the total size) with joints ). If no other options are specified, this option is the default value.

Only the/headers dumpbin option can be used for files generated by the/GL compiler option.

/SYMBOLS

This option displays the coff symbol table. Symbol tables exist in all object files. For an image file, it only contains the coff symbol table when it is linked to/debug.

The following is a description of/Symbols output. You can find additional information about the/Symbols output meaning by reading winnt. H (image_symbol and image_aux_symbol) or coff documents.

Assume that the following sample dump is available:

For rows starting with a symbolic number, the following describes the columns containing user-related information:

• The three digits at the beginning are symbol indexes/numbers.
• If the third column contains SectXThe symbol is defined in the section of the object file. However, if UNDEF appears, it is not defined in that object and must be parsed elsewhere.
• The Fifth Column (static, external) indicates whether the symbol is only visible inside the object, or whether it is public (externally visible ). The static symbol _ sym is not linked to the public symbol _ sym. These symbols are two different instances of the function named _ sym.

The last column in the number row is the symbol name (modifier name and unmodifyed name ).

Only the/headers dumpbin option can be used for files generated by the/GL compiler option.

/Unwindinfo

Dump the expansion descriptor of the structured exception processing (seh) table in the program image (such as EXE and DLL. /Unwindinfo is only applicable to IA64 images.

Only the/headers dumpbin option can be used for files generated by the/GL compiler option.
