NAME

       sctp_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 descrip-
       tor. 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 associations for sock.

       EMFILE	       Failure to create a new user file descriptor or file structure.
