Parameters

s	The stream to read data from
wcharLength	The number of WCHAR characters to read (NOT the size in bytes!)
utfBuffer	A pointer to a buffer holding the result string
utfBufferCharLength	The size of the result buffer

Returns: The char length (strlen) of the result string or -1 for failure

		size_t	length,
		BOOL	fill
	)

Writes a UTF-8 string UTF16 encoded to the stream. If the UTF-8 string is short, the remainig characters are filled up with '\0'.

Parameters

s	The stream to write to
wcharLength	the length (in WCHAR characters) to write
src	The source data buffer with the UTF-8 data
length	The length in bytes of the UTF-8 buffer
fill	If TRUE fill the unused parts of the wcharLength with 0

return number of used characters for success, /b -1 for failure
