IXCLRDataStackWalk::Request Method

  • Article

Requests to populate the buffer given with the process's data.

Note

This API was originally designed for internal use in the runtime. Although it is now supported for 3rd party use, we recommend working with ICorDebug and ICorProfiler APIs when possible.

Syntax

HRESULT Request(
    [in] ULONG32 reqCode,
    [in] ULONG32 inBufferSize,
    [in, size_is(inBufferSize)] BYTE* inBuffer,
    [in] ULONG32 outBufferSize,
    [out, size_is(outBufferSize)] BYTE* outBuffer);

Parameters

reqCode
[in] Request type to be sent.

Requests can be one of the following:

Member Value Description
CLRDATA_REQUEST_REVISION 0xe0000000 Request the revision of the stack walk. The revision is a ULONG32 numeric value.
CLRDATA_STACK_WALK_REQUEST_SET_FIRST_FRAME 0xe1000000 Tell the stack walker whether the current state represents the first frame of the stack or not. The value is a ULONG32 boolean value. Note that callers of SetContext may use this to indicate to the stack walker whether the set register context represents the real register context of a thread or some intermediate unwind.

inBufferSize
[in] size of the input buffer to be passed in.

inBuffer
[in, size_is(inBufferSize)] Buffer pointer for the raw data to be sent in the request.

outBufferSize
[in] Size of the output buffer.

outBuffer
[out, size_is(outBufferSize)] Buffer pointer to used to store the request response.

Remarks

The provided method is part of the IXCLRDataStackWalk interface and corresponds to the 10th slot of the virtual method table.
