◆ Register()

EFI_STATUS EFIAPI Register ( IN EFI_MM_RSC_HANDLER_CALLBACK Callback )

Register the callback function for ReportStatusCode() notification.

When this function is called the function pointer is added to an internal list and any future calls to ReportStatusCode() will be forwarded to the Callback function.

Parameters

[in] Callback A pointer to a function of type EFI_PEI_RSC_HANDLER_CALLBACK that is called when a call to ReportStatusCode() occurs.

Return values

EFI_SUCCESS	Function was successfully registered.
EFI_INVALID_PARAMETER	The callback function was NULL.
EFI_OUT_OF_RESOURCES	The internal buffer ran out of space. No more functions can be registered.
EFI_ALREADY_STARTED	The function was already registered. It can't be registered again.

◆ ReportDispatcher()

EFI_STATUS EFIAPI ReportDispatcher	(	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
	)

Provides an interface that a software module can call to report a status code.

Parameters

This	EFI_MM_STATUS_CODE_PROTOCOL instance.
CodeType	Indicates the type of status code being reported.
Value	Describes the current status of a hardware or software entity. This included information about the class and subclass that is used to classify the entity as well as an operation.
Instance	The enumeration of a hardware or software entity within the system. Valid instance numbers start with 1.
