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
The sock argument is not a one-to-many style SCTP
socket.
EINVAL
The id is 0 or greater than the maximum
number of associations for sock.
EMFILE
Failure to create a new user file descriptor or file
structure.
