  31   Internal worker function that reports a status code through the Status Code Protocol
  32
  33   This function checks to see if a Status Code Protocol is present in the handle
  34   database.  If a Status Code Protocol is not present, then EFI_UNSUPPORTED is
  35   returned.  If a Status Code Protocol is present, then it is cached in gStatusCode,
  36   and the ReportStatusCode() service of the Status Code Protocol is called passing in
  37   Type, Value, Instance, CallerId, and Data.  The result of this call is returned.

  44                             NULL.
  45   @param  Data              Pointer to the extended data buffer.  This is an
  46                             optional parameter that may be NULL.

  65   The function reports a status code.  If ExtendedData is NULL and ExtendedDataSize
  66   is 0, then an extended data buffer is not reported.  If ExtendedData is not
  67   NULL and ExtendedDataSize is not 0, then an extended data buffer is allocated.
  68   ExtendedData is assumed not have the standard status code header, so this function
  69   is responsible for allocating a buffer large enough for the standard header and
  70   the extended data passed into this function.  The standard header is filled in
  71   with a GUID specified by ExtendedDataGuid.  If ExtendedDataGuid is NULL, then a
  72   GUID of gEfiStatusCodeSpecificDatauid is used.  The status code is reported with
  73   an instance specified by Instance and a caller ID specified by CallerId.  If
  74   CallerId is NULL, then a caller ID of gEfiCallerIdGuid is used.
  75
  76   ReportStatusCodeEx()must actively prevent recursion.  If ReportStatusCodeEx()
  77   is called while processing another any other Report Status Code Library function,
  78   then ReportStatusCodeEx() must return EFI_DEVICE_ERROR immediately.

  88                             ID of gEfiCallerIdGuid is used.
