The Request method performs a variety of different operations.

Syntax


HRESULT Request(
  [in]            ULONG  Request,
  [in, optional]  PVOID  InBuffer,
  [in]            ULONG  InBufferSize,
  [out, optional] PVOID  OutBuffer,
  [in]            ULONG  OutBufferSize,
  [out, optional] PULONG OutSize
);

Parameters

Request [in]

Specifies which operation to perform. Request can be one of the values in the following table. Details of each operation can be found by following the link in the "Request" column.

RequestAction

DEBUG_REQUEST_SOURCE_PATH_HAS_SOURCE_SERVER

Check the source path for a source server.

DEBUG_REQUEST_TARGET_EXCEPTION_CONTEXT

Return the thread context for the stored event in a user-mode minidump file.

DEBUG_REQUEST_TARGET_EXCEPTION_THREAD

Return the operating system thread ID for the stored event in a user-mode minidump file.

DEBUG_REQUEST_TARGET_EXCEPTION_RECORD

Return the exception record for the stored event in a user-mode minidump file.

DEBUG_REQUEST_GET_ADDITIONAL_CREATE_OPTIONS

Return the default process creation options.

DEBUG_REQUEST_SET_ADDITIONAL_CREATE_OPTIONS

Set the default process creation options.

DEBUG_REQUEST_GET_WIN32_MAJOR_MINOR_VERSIONS

Return the version of Windows that is currently running on the target.

DEBUG_REQUEST_READ_USER_MINIDUMP_STREAM

Read a stream from a user-mode minidump target.

DEBUG_REQUEST_TARGET_CAN_DETACH

Check to see if it is possible for the debugger engine to detach from the current process (leaving the process running but no longer being debugged).

DEBUG_REQUEST_SET_LOCAL_IMPLICIT_COMMAND_LINE

Set the debugger engine's implicit command line.

DEBUG_REQUEST_GET_CAPTURED_EVENT_CODE_OFFSET

Return the current event's instruction pointer.

DEBUG_REQUEST_READ_CAPTURED_EVENT_CODE_STREAM

Return up to 64 bytes of memory at the current event's instruction pointer.

DEBUG_REQUEST_EXT_TYPED_DATA_ANSI

Perform a variety of different operations that aid in the interpretation of typed data.

 

InBuffer [in, optional]

Specifies the input to this method. The type and interpretation of the input depends on the Request parameter.

InBufferSize [in]

Specifies the size of the input buffer InBuffer. If the request requires no input, InBufferSize should be set to zero.

OutBuffer [out, optional]

Receives the output from this method. The type and interpretation of the output depends on the Request parameter. If OutBuffer is NULL, the output is not returned.

OutBufferSize [in]

Specifies the size of the output buffer OutBufferSize. If the type of the output returned to OutBuffer has a known size, OutBufferSize is usually expected to be exactly that size, even if OutBuffer is set to NULL.

OutSize [out, optional]

Receives the size of the output returned in the output buffer OutBuffer. If OutSize is NULL, this information is not returned.

Return value

The interpretation of the return value depends on the value of the Request parameter. Unless otherwise stated, the following values may be returned.

Return codeDescription
S_OK

The method was successful.

S_FALSE

The method was successful. However, the output would not fit in the output buffer OutBuffer, so truncated output was returned.

E_INVALIDARG

The size of the input buffer InBufferSize or the size of the output buffer OutBufferSize was not the expected value.

 

This method may also return error values. See Return Values for more details.
