WerRegisterExcludedMemoryBlock function

Marks a memory block (that is normally included by default in error reports) to be excluded from the error report.

Syntax

HRESULT WerRegisterExcludedMemoryBlock(
  const void *address,
  DWORD      size
);

Parameters

address

The starting address of the memory block.

size

The size of the memory block, in bytes.

Return Value

This function returns S_OK on success or an error code on failure, including the following error codes.

Return code Description
E_INVALIDARG
address is NULL or size is 0.
E_OUTOFMEMORY
WER could not allocate a large enough heap for the data
HRESULT_FROM_WIN32(ERROR_INSUFFICIENT_BUFFER)
The number of registered entries exceeds the limit (WER_MAX_REGISTERED_ENTRIES).
WER_E_INVALID_STATE
The process state is not valid. For example, the process is in application recovery mode.

Remarks

This mechanism is intended for applications that hold large amounts of data in memory that aren't useful for root cause debugging and increase the size of the dump file unnecessarily. For example, some Xbox One games hold large amounts of texture data in memory that is included in error dumps by default.
