439 | \r | |
440 | The function reports a status code. If ExtendedData is NULL and ExtendedDataSize\r | |
441 | is 0, then an extended data buffer is not reported. If ExtendedData is not\r | |
442 | NULL and ExtendedDataSize is not 0, then an extended data buffer is allocated.\r | |
443 | ExtendedData is assumed not have the standard status code header, so this function\r | |
444 | is responsible for allocating a buffer large enough for the standard header and\r | |
445 | the extended data passed into this function. The standard header is filled in\r | |
446 | with a GUID specified by ExtendedDataGuid. If ExtendedDataGuid is NULL, then a\r | |
447 | GUID of gEfiStatusCodeSpecificDataGuid is used. The status code is reported with\r | |
448 | an instance specified by Instance and a caller ID specified by CallerId. If\r | |
449 | CallerId is NULL, then a caller ID of gEfiCallerIdGuid is used.\r | |
450 | \r | |
451 | ReportStatusCodeEx()must actively prevent recursion. If\r | |
452 | ReportStatusCodeEx() is called while processing another any\r | |
453 | other Report Status Code Library function, then\r | |
454 | ReportStatusCodeEx() must return EFI_DEVICE_ERROR immediately.\r | |
