As previously mentioned, it is possible to extract an association contained by a one-to-many socket into an individual one-to-one-style socket. The semantics are much like the accept function call with an additional argument. The caller passes the
sockfd of the one-to-many socket and the association identification
id that is being extracted. At the completion of the call, a new socket descriptor is returned. This new descriptor will be a one-to-one-style socket descriptor with the requested association. The function takes the following form:
int sctp_peeloff(int sockfd , sctp_assoc_t id ); |
Returns: a new socket descriptor on success, 1 on error |
