3.1.4.3.6.2 CLUSCTL_NETINTERFACE_GET_CHARACTERISTICS
The CLUSCTL_NETINTERFACE_GET_CHARACTERISTICS cluster network interface control code retrieves the intrinsic characteristics of the designated cluster network interface. A cluster network interface MUST NOT have any characteristics.
After the successful completion of this method, the server MUST write the CLUS_CHAR_UNKNOWN value, as specified in section 2.2.2.4, to the buffer that is indicated by lpOutBuffer.
The server SHOULD accept a CLUSCTL_NETINTERFACE_GET_CHARACTERISTICS cluster network interface control code request if its protocol server state is read-only, and the server MUST accept the request for processing if it is in the read/write state, as specified in section 3.1.1.
