Parameters

Source

Points to the string to be appended to the Destination string.

Return Value

RtlAppendUnicodeToString can return one of the following status codes:

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

Comments

The Destination buffer must be resident if the caller is running at IRQL >= DISPATCH_LEVEL.
