sctp_peeloff - branch off existing association from a one-to-many SCTP socket to create a one-to-one STP socket

int sctp_peeloff(int sock, sctp_assoc_t id);

The sctp_peeloff() function branches off an existing association from a one-to-many style SCTP socket into a separate socket file descriptor. The resulting branched-off socket is a one-to-one style SCTP socket and is confined to operations allowed on a one-to-one style SCTP socket.

The sock argument is a one-to-many socket. The association specified by the id argument is branched off sock.

Upon successful completion, the sctp_peeloff() function returns the file descriptor that references the branched-off socket. The function returns -1 if an error occurs.

The sctp_peeloff() function fails under the following conditions. EOPTNOTSUPP

EINVAL EMFILE
