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 gEfiStatusCodeSpecificDatauid 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().
@param Type Status code type.
@param Value Status code value.
@param Instance Status code instance number.
@param 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.
@param 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.
@param ExtendedData Pointer to the extended data buffer. This is an
optional parameter that may be NULL.
@param ExtendedDataSize The size, in bytes, of the extended data buffer.
@retval EFI_SUCCESS The status code was reported.
@retval EFI_OUT_OF_RESOURCES There were not enough resources to allocate
the extended data section if it was specified.
@retval EFI_UNSUPPORTED Report status code is not supported
