Return Value

RtlAppendUnicodeStringToString can return one of the following values:

Value	Meaning
STATUS_SUCCESS	The source string was successfully appended to the destination counted string.
STATUS_BUFFER_TOO_SMALL	The destination string length is too small to allow the source string to be concatenated. Accordingly, the destination string length is not updated.
