2.2.3.9 CPMFetchValueOut
The CPMFetchValueOut message replies to a CPMFetchValueIn message with a metadata about the most recent previously issued query. As specified in section 3.1.5.4, this message is sent after each CPMFetchValueIn message until all bytes of the metadata are transferred. The message length including header MUST be less than or equal to the value of _cbChunk specified in the CPMFetchValueIn message.
The format of the CPMFetchValueOut message that follows the header is shown in the following diagram.
