◆ EFI_MM_REPORT_STATUS_CODE

typedef EFI_STATUS(EFIAPI * EFI_MM_REPORT_STATUS_CODE) (IN CONST EFI_MM_STATUS_CODE_PROTOCOL *This, IN EFI_STATUS_CODE_TYPE CodeType, IN EFI_STATUS_CODE_VALUE Value, IN UINT32 Instance, IN CONST EFI_GUID *CallerId, IN EFI_STATUS_CODE_DATA *Data OPTIONAL)

Service to emit the status code in MM.

The EFI_MM_STATUS_CODE_PROTOCOL.ReportStatusCode() function enables a driver to emit a status code while in MM. The reason that there is a separate protocol definition from the DXE variant of this service is that the publisher of this protocol will provide a service that is capability of coexisting with a foreground operational environment, such as an operating system after the termination of boot services.
