_RECORDER_LOG_CREATE_PARAMS structure

Description

The RECORDER_LOG_CREATE_PARAMS structure is an input parameter to the WppRecorderLogCreate method.

Members

`Size`

Size of this structure.

`LogTag`

Optional tag to associate with the allocated memory of the log.

`TotalBufferSize`

Size in bytes for the log area.

`ErrorPartitionSize`

The number of bytes out of TotalBufferSize used to log error messages. Zero indicates no error partition.

`LogIdentifierAppendValue`

Number/pointer to append to log identifier.

`LogIdentifierAppendValueSet`

Specifies whether LogIdentifierAppendValue has been set.

`LogIdentifierSize`

Size of LogIdentifier field, in bytes (according to client's definition).

`LogIdentifier`

Identifier to print when debug messages are merged. Lives at end of structure so that, if at some point clients have different definitions of the array size, it remains simple to read the rest of the structure.

`UseTimeStamp`

A WPP_RECORDER_TRI_STATE-typed value that indicates:

If set to WppRecorderTrue, timestamps of millisecond granularity will be added to WPP log entries.
If set to WppRecorderFalse, the timestamp will not be recorded.
If set to WppRecorderDefault, it has the same effect as WppRecorderFalse, unless the INF file for the driver package sets WppRecorder_UseTimeStamp to 1, in which case it means WppRecorderTrue.

This field is available starting in Windows 11, version 22H2. For more info, see Inflight Trace Recorder (IFR) for logging traces.

`PreciseTimeStamp`
