That's very helpful info. Thanks! So getsockname() and getpeername() returns the initial subflow, what's the API to get other subflows?
Edit: found my answer: https://datatracker.ietf.org/doc/rfc6897/?include_text=1 by using setsockopt() and getsockopt() The functions getpeername() and getsockname() SHOULD also always return the addresses of the first subflow if the socket is used by an MPTCP-aware application, in order to be consistent with MPTCP-unaware applications, and, e.g., also with the Stream Control Transmission Protocol (SCTP). Instead of getpeername() or getsockname(), MPTCP-aware applications can use new API calls, described in Section 5.3, in order to retrieve the full list of address pairs for the subflows in use.
