ICLRDataTarget3::GetExceptionContextRecord Method

Article
09/15/2021

Called by the common language runtime (CLR) data access services to retrieve the context record associated with the target process. For example, for a dump target, this would be equivalent to the context record passed in via the ExceptionParam argument to the MiniDumpWriteDump function in the Windows Debug Help Library (DbgHelp).

Syntax

HRESULT GetExceptionContextRecord(
    [in] ULONG32 bufferSize,
    [out] ULONG32* bufferUsed,
    [out, size_is(bufferSize)] BYTE* buffer
);

Parameters

bufferSize [in] The input buffer size, in bytes. This must be large enough to accommodate the context record.

bufferUsed [out] A pointer to a ULONG32 type that receives the number of bytes actually written to the buffer.

buffer [out] A pointer to a memory buffer that receives a copy of the context record. The exception record is returned as a CONTEXT type.

Return Value

The return value is S_OK on success, or a failure HRESULT code on failure. The HRESULT codes can include but are not limited to the following:

Return code	Description
`S_OK`	Method succeeded. The context record has been copied to the output buffer.
`HRESULT_FROM_WIN32(ERROR_NOT_FOUND)`	No context record is associated with the target.
`HRESULT_FROM_WIN32(ERROR_BAD_LENGTH)`	The input buffer size is not large enough to accommodate the context record.

Remarks

CONTEXT is a platform-specific structure defined in headers provided by the Windows SDK.

This method is implemented by the writer of the debugging application.
