Gets information that identifies the structured XML query that selected the event and the channel or log file that contained the event.

Syntax

BOOL EvtGetEventInfo(
  [in]  EVT_HANDLE            Event,
  [in]  EVT_EVENT_PROPERTY_ID PropertyId,
  [in]  DWORD                 PropertyValueBufferSize,
  [in]  PEVT_VARIANT          PropertyValueBuffer,
  [out] PDWORD                PropertyValueBufferUsed
);

Parameters

[in] Event

A handle to an event for which you want to retrieve information.

[in] PropertyId

A flag that identifies the information to retrieve. For example, the query identifier or the path. For possible values, see the EVT_EVENT_PROPERTY_ID enumeration.

[in] PropertyValueBufferSize

The size of the PropertyValueBuffer buffer, in bytes.

[in] PropertyValueBuffer

A caller-allocated buffer that will receive the information. The buffer contains an EVT_VARIANT object. You can set this parameter to NULL to determine the required buffer size.

[out] PropertyValueBufferUsed

The size, in bytes, of the caller-allocated buffer that the function used or the required buffer size if the function fails with ERROR_INSUFFICIENT_BUFFER.

Return value

Return code/value	Description
TRUE	The function succeeded.
FALSE	The function failed. Use the GetLastError function to get the error code.

Remarks

If the query that you passed to EvtQuery or EvtSubscribe was an XPath instead of a structured XML query, the query identifier will be zero and the path will be the path that you passed to the function.
