Point to Runtime memory table header.

@param CodeType Indicates the type of status code being reported. Type EFI_STATUS_CODE_TYPE is defined in "Related Definitions¡± below.
|
|
|
|
@param 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. For progress codes, the operation is the current activity.
|
|
For error codes, it is the exception. For debug codes, it is not defined at this time.

Type EFI_STATUS_CODE_VALUE is defined in ¡°Related Definitions¡± below.
|

Specific values are discussed in the Intel? Platform Innovation Framework for EFI Status Code Specification.

|
|
@param Instance The enumeration of a hardware or software entity within the system.
|
|
A system may contain multiple entities that match a class/subclass pairing.
|
|
The instance differentiates between them. An instance of 0 indicates that instance information is unavailable,
|
|
not meaningful, or not relevant. Valid instance numbers start with 1.
