3.1.1.1 String Handling

The data model for storing an attribute of syntax "string" is a UTF-16 encoded string not including the terminating null character. In this protocol, a string is represented within an RPC_UNICODE_STRING structure, which is a counted string.

When a string to be stored in the database arrives through this protocol, it MUST be processed such that the database attribute is updated with RPC_UNICODE_STRING.Length bytes of RPC_UNICODE_STRING.Buffer.

When a database attribute is to be returned as an RPC_UNICODE_STRING via this protocol, RPC_UNICODE_STRING.Length MUST be the count of bytes stored in the database for that attribute, and RPC_UNICODE_STRING.Buffer MUST contain the database value for that attribute.

In addition, when receiving an RPC_UNICODE_STRING or RPC_STRING, if the Length field is nonzero and the Buffer field is NULL, an error MUST be returned.
