IDebugClient2::WriteDumpFile2 method (dbgeng.h)
The WriteDumpFile2 method creates a user-mode or kernel-modecrash dump file.
Syntax
HRESULT WriteDumpFile2(
[in] PCSTR DumpFile,
[in] ULONG Qualifier,
[in] ULONG FormatFlags,
[in, optional] PCSTR Comment
);
Parameters
[in] DumpFile
Specifies the name of the dump file to create. DumpFile must include the file name extension. DumpFile can include a relative or absolute path; relative paths are relative to the directory in which the debugger was started.
[in] Qualifier
Specifies the type of dump file to create. For possible values, see DEBUG_DUMP_XXX.
[in] FormatFlags
Specifies flags that determine the format of the dump file and--for user-mode minidumps--what information to include in the file. For details, see Remarks.
[in, optional] Comment
Specifies a comment string to be included in the crash dump file. This string is displayed in the debugger console when the dump file is loaded. Some dump file formats do not support the storing of comment strings.
Return value
This method may also return error values. See Return Values for more details.

Remarks
The DEBUG_FORMAT_XXX bit-flags are used by WriteDumpFile2 and WriteDumpFileWide to determine the format of a crash dump file and, for user-mode Minidumps, what information to include in the file.
The following bit-flags apply to all crash dump files.
| Value | Description |
|---|---|
| DEBUG_FORMAT_WRITE_CAB | Package the crash dump file in a CAB file. The supplied file name or file handle is used for the CAB file; the crash dump is first created in a temporary file before being moved into the CAB file. |
| DEBUG_FORMAT_CAB_SECONDARY_FILES |
|
| DEBUG_FORMAT_NO_OVERWRITE | Do not overwrite existing files. |
The following bit-flags can also be included for user-mode Minidumps.
| Value | Description |
|---|---|
| DEBUG_FORMAT_USER_SMALL_FULL_MEMORY | Add full memory data. All accessible committed pages owned by the target application will be included. |
| DEBUG_FORMAT_USER_SMALL_HANDLE_DATA | Add data about the handles that are associated with the target application. |
| DEBUG_FORMAT_USER_SMALL_UNLOADED_MODULES | Add unloaded module information. This information is available only in Windows Server 2003 and later versions of Windows. |
| DEBUG_FORMAT_USER_SMALL_INDIRECT_MEMORY | Add indirect memory. A small region of memory that surrounds any address that is referenced by a pointer on the stack or backing store is included. |
| DEBUG_FORMAT_USER_SMALL_DATA_SEGMENTS | Add all data segments within the executable images. |
| DEBUG_FORMAT_USER_SMALL_FILTER_MEMORY | Set to zero all of the memory on the stack and in the backing store that is not useful for recreating the stack trace. This can make compression of the Minidump more efficient and increase privacy by removing unnecessary information. |
| DEBUG_FORMAT_USER_SMALL_FILTER_PATHS | Remove the module paths, leaving only the module names. This is useful for protecting privacy by hiding the directory structure (which may contain the user's name). |
| DEBUG_FORMAT_USER_SMALL_PROCESS_THREAD_DATA | Add the process environment block (PEB) and thread environment block (TEB). This flag can be used to provide Windows system information for threads and processes. |
| DEBUG_FORMAT_USER_SMALL_PRIVATE_READ_WRITE_MEMORY | Add all committed private read-write memory pages. |
| DEBUG_FORMAT_USER_SMALL_NO_OPTIONAL_DATA |
|
| DEBUG_FORMAT_USER_SMALL_FULL_MEMORY_INFO | Add all basic memory information. This is the information returned by the QueryVirtual method. The information for all memory is included, not just valid memory, which allows the debugger to reconstruct the complete virtual memory layout from the Minidump. |
| DEBUG_FORMAT_USER_SMALL_THREAD_INFO | Add additional thread information, which includes execution time, start time, exit time, start address, and exit status. |
| DEBUG_FORMAT_USER_SMALL_CODE_SEGMENTS | Add all code segments with the executable images. |
