Syntax

TdhGetAllEventsInformation(
    __in PEVENT_RECORD pEvent,
    __in_opt PVOID pWbemService,
    __out ULONG *pIndex,
    __out ULONG *pCount,
    __out_bcount_opt(*pBufferSize) PTRACE_EVENT_INFO *ppBuffer,
    __inout ULONG *pBufferSize
    );

Parameters

pEvent [in]

The event record passed to your EventRecordCallback callback. For details, see the EVENT_RECORD structure.

pWbemService [in]

Pointer to namespace for which the diagnostic mode data is retrieved.

pIndex [out]

The index in the ppBuffer buffer of the first PTRACE_EVENT_INFO.

pCount

The number of PTRACE_EVENT_INFO entries returned in ppBuffer.

ppBuffer

User-allocated buffer to receive the event information. For details, see the TRACE_EVENT_INFO structure.

pBufferSize

Size, in bytes, of the pBuffer buffer. If the function succeeds, this parameter receives the size of the buffer used. If the buffer is too small, the function returns ERROR_INSUFFICIENT_BUFFER and sets this parameter to the required buffer size. If the buffer size is zero on input, no data is returned in the buffer and this parameter receives the required buffer size.

Return value

S_OK on success.
