◆ utf8to16()

static wchar_t * utf8to16 ( const char * utf8 )

inlinestatic

Convert a zero terminated UTF-8 string to UTF-16.

This is just a wrapper function that always passes -1 as string size to utf8to16_size.

Parameters

utf8	const string to be converted

Returns: wchar_t* heap allocated result string

Definition at line 123 of file service.h.

References utf8to16_size().

Referenced by HandleDNSConfigMessage(), HandleWINSConfigMessage(), InterfaceLuid(), and SetDNSDomain().

◆ utf8to16_size()

wchar_t * utf8to16_size	(	const char *	utf8,
		int	size
	)

Convert a UTF-8 string to UTF-16.

The size parameter can be used to convert strings which contain inline NUL characters, like MULTI_SZ strings used as values in the registry do, or (sub)strings that are not zero terminated. If size is -1 the length of the string is determined automatically by the WIN32 API. Make sure you pass a terminated string or else bad things will happen. Note that the size you pass should always include the terminating zero as well.

If the returned string is not NULL it must be freed by the caller.

Parameters

utf8	const string to be converted
size	the size of the string

Returns: wchar_t* heap allocated result string
