SCTP_PEELOFF(3SOCKET)SCTP_PEELOFF(3SOCKET)NAMEsctp_peeloff - branch off existing association from a one-to-many SCTP
socket to create a one-to-one STP socket
SYNOPSIS
cc [ flag... ] file... -lsocket -lnsl -lsctp [ library... ]
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/sctp.h>
int sctp_peeloff(int sock, sctp_assoc_t id);
DESCRIPTION
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.
RETURN VALUES
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.
ERRORS
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 asso‐
ciations for sock.
EMFILE
Failure to create a new user file descriptor or file
structure.
