		IN CONST VOID *ExtendedData	OPTIONAL,
		IN UINTN	ExtendedDataSize
	)

Reports a status code with full parameters.

The function reports a status code. If ExtendedData is NULL and ExtendedDataSize is 0, then an extended data buffer is not reported. If ExtendedData is not NULL and ExtendedDataSize is not 0, then an extended data buffer is allocated. ExtendedData is assumed not have the standard status code header, so this function is responsible for allocating a buffer large enough for the standard header and the extended data passed into this function. The standard header is filled in with a GUID specified by ExtendedDataGuid. If ExtendedDataGuid is NULL, then a GUID of gEfiStatusCodeSpecificDataGuid is used. The status code is reported with an instance specified by Instance and a caller ID specified by CallerId. If CallerId is NULL, then a caller ID of gEfiCallerIdGuid is used.

ReportStatusCodeEx()must actively prevent recursion. If ReportStatusCodeEx() is called while processing another any other Report Status Code Library function, then ReportStatusCodeEx() must return EFI_DEVICE_ERROR immediately.

If ExtendedData is NULL and ExtendedDataSize is not zero, then ASSERT(). If ExtendedData is not NULL and ExtendedDataSize is zero, then ASSERT().

Parameters

Type	Status code type.
Value	Status code value.
Instance	Status code instance number.
CallerId	Pointer to a GUID that identifies the caller of this function. If this parameter is NULL, then a caller ID of gEfiCallerIdGuid is used.
ExtendedDataGuid	Pointer to the GUID for the extended data buffer. If this parameter is NULL, then a the status code standard header is filled in with gEfiStatusCodeSpecificDataGuid.
ExtendedData	Pointer to the extended data buffer. This is an optional parameter that may be NULL.
ExtendedDataSize	The size, in bytes, of the extended data buffer.

Return values

EFI_SUCCESS	The status code was reported.
