Public Functions
`SFCError`	ReadSFXAnsiString( `SFXAnsiStringPtr` param ) Read data from the input stream as a SFXWideString string, and convert it into SFXAnsiString.
`SFCError`	ReadSFXWideString( `SFXWideStringPtr` param ) Read data from the input stream as a SFXWideString string.
`SFXWideStringStreamReaderRef`	operator>>( `SFXWideStringStreamReaderRef` left , `SFXWideStringRef` right ) operator>>( `SFXWideStringStreamReaderRef` left , `SFXAnsiStringRef` right ) Read data from the input stream as a SFXWideString string.
`Void`	Attach( `SFXInputStreamPtr` stream ) (inherits from SFXStreamReader) Delegate the control privilege of SFXInputStream object to the SFXStreamReader object.
`Void`	Cancel( `Void` ) (inherits from SFXStreamReader) Call the Cancel function for Storage class. And also unregister the callback functions.
`SFXInputStreamPtr`	Detach( `Void` ) (inherits from SFXStreamReader) Delegate the control privilege of SFXStreamReader object to the SFXInputStream object.
`Bool`	Ends( `Void` ) (inherits from SFXStreamReader) Check whether the stream ends or not.
`SFCError`	Fetch( `Void` ) (inherits from SFXStreamReader) Fetch( `CallbackSPP` spp , `VoidPtr` reference ) (inherits from SFXStreamReader) Fetch for reading data newly.

`UInt32`	GetReadableSize( `Void` ) (inherits from SFXStreamReader) Get the size of readable data.
`SInt32`	LastIndexOf( `Byte` byte , `SInt32` index = SINT32_MAXIMUM ) (inherits from SFXStreamReader) LastIndexOf( `VoidConstPtr` buffer , `UInt32` size , `SInt32` index = SINT32_MAXIMUM ) (inherits from SFXStreamReader) LastIndexOf( `SFXBufferConstRef` buffer , `SInt32` index = SINT32_MAXIMUM ) (inherits from SFXStreamReader) Get the last index of SFXStreamReader object to match with the specified data, searching from the end.
`SFCError`	Read( `SFXBufferPtr` buffer ) (inherits from SFXStreamReader) Read( `VoidPtr` buffer , `UInt32` size ) (inherits from SFXStreamReader) Read data from the stream.
`Void`	Release( `Void` ) (inherits from SFXStreamReader) Release the stream.
`SFCError`	ResetTrigger( `Void` ) (inherits from SFXStreamReader) Reset the trigger when the callback function will be called.
`SFCError`	Seek( `UInt32` size ) (inherits from SFXStreamReader) Move the read pointer foraward.
`SFCError`	SetTrigger( `UInt32` size ) (inherits from SFXStreamReader) SetTrigger( `VoidConstPtr` buffer , `UInt32` size ) (inherits from SFXStreamReader) SetTrigger( `SFXBufferConstRef` buffer ) (inherits from SFXStreamReader) Set the trigger when the callback function will be called.
`Bool`	Triggers( `Void` ) (inherits from SFXStreamReader) Check whether the callback function is called by trigger or not.

Types
CallbackSPP (inherits from SFXStream) Constant that represents Callback function.

SFXWideStringStreamReader::SFXWideStringStreamReader

Constructor of SFXWideStringStreamReader class.

[ public, explicit ]
SFXWideStringStreamReader(Void);

SFXWideStringStreamReader::ReadSFXAnsiString

Read data from the input stream as a SFXWideString string, and convert it into SFXAnsiString.

[ public ]
SFCError ReadSFXAnsiString(
    SFXAnsiStringPtr param   // pointer to the resault
);

Return value

Success : SFERR_NO_ERROR
If stream is not set : SFERR_INVALID_STATE
If argument is null : SFERR_INVALID_PARAM
If insufficient memory : SFERR_NO_MEMORY
If failed : SFERR_FAILED

Description

Read data as a string until the next "\0"

If no "\0" is found until the end, read data as a string until the end.
