@param MiscOnboardDevice The string which is used to create the function
|
|
The Arguments in fact:
|

|
|
@param RecordLen Size of static RecordData from the Data Table.
|
|
mMiscSubclassDataTable[].RecordLen
|
|
@param RecordData Pointer to RecordData, which will be written to
|
|
the Data Hub
|
|
@param LogRecordData TRUE to log RecordData to Data Hub. FALSE when
|
|
there is no more data to log.
|
|
|
|
@retval EFI_SUCCESS *RecordData and *LogRecordData have been set.
|
|
@retval EFI_UNSUPPORTED Unexpected RecordType value.
|
|
@retval EFI_INVALID_PARAMETER One of the following parameter conditions was
|
|
true: RecordLen was zero. RecordData was NULL.
