When a connection to a note pad is successfully created, XCF constructs a unique 12 byte connection identifier to represent the connection. The connection identifier is not the same as the connection token. The connection identifier can be obtained from the answer area (if any) returned by the IXCNOTE request that created the connection. When a note is created or replaced in the note pad, the connection that issued the request becomes associated with the note. The connection identifier is used to identify the associated connection. The connection identifier of the connection associated with a note can be obtained from the answer area (if any) returned by an IXCNOTE request that processes the note.

When reading or deleting a collection of notes, you can provide selection criteria to identify the notes to be processed. One of the possible selection criteria is connection identifier. Thus your program could issue a request to read (or delete) all of the notes in the note pad associated with a given connection identifier.
