ensure_trailing_backslash()

BOOL ensure_trailing_backslash ( PWSTR dir, size_t size )

static

Make sure that a dir path ends with a backslash.

If it doesn't, a \ is added to the end of the path, if there's room in the buffer.

Parameters

dir	pointer to the wide dir path string buffer
size	maximum number of wide chars the dir path buffer

Returns

BOOL to indicate success or failure

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
