|

|

The ASL parameters "ReturnType" and "ParameterTypes" are not asked
|

in this function. They are optional parameters in ASL.
|

|

@param [in] MethodNameString The new Method's name.
|
||||
Must be a NULL-terminated ASL NameString
|
||||
e.g.: "MET0", "_SB.MET0", etc.
|
||||
The input string is copied.
|
||||
@param [in] ReturnedNameString The name of the object returned by the
|
||||
method. Optional parameter, can be:
|
||||
- NULL (ignored).
|
||||
- A NULL-terminated ASL NameString.
|

e.g.: "MET0", "_SB.MET0", etc.
|

The input string is copied.
|

@param [in] NumArgs Number of arguments.
|
||||
Must be 0 <= NumArgs <= 6.
|
||||
@param [in] IsSerialized TRUE is equivalent to Serialized.
|
||||
FALSE is equivalent to NotSerialized.
|
||||
Default is NotSerialized in ASL spec.
|
||||
@param [in] SyncLevel Synchronization level for the method.
|

Must be 0 <= SyncLevel <= 15.
|
||||
Default is 0 in ASL.
|

@param [in] IntegerArgument Argument to pass to the NameString.
|
||||
@param [in] ParentNode If provided, set ParentNode as the parent
|
||||
of the node created.
|

@param [out] NewObjectNode If success, contains the created node.

@retval EFI_SUCCESS Success.

@retval EFI_INVALID_PARAMETER Invalid parameter.
