sctp_peeloff - Branch off an association into a separate socket.

sctp_peeloff  branches  off  an  existing  association  assoc_id  on a one-to-many style socket sd into a
       separate socket. The new socket is a one-to-one style socket.

       This is particularly desirable when, for instance, the application wishes to have a  number  of  sporadic
       message  senders/receivers  remain  under  the  original  one-to-many  style socket, but branch off those
       assocations carrying high volume data traffic into their own separate socket descriptors.

       sctp_peeloff_flags is a variant of sctp_peeloff, in which flags describing  the  behavior  of  the  newly
       peeled off socket can be specified.  Currently the supported flags are:

       SOCK_NONBLOCK
              Specifies that the new socket should not block on io operations.

       SOCK_CLOEXEC
              Specifies that the new socket should be closed when the owning process calls exec.

EBADFsd is not a valid descriptor.

       EINVAL The assoc id passed is invalid or if the socket is a one-to-one style socket.

       ENOTSOCK
              Argument is a descriptor for a file, not a socket.

       sctp_peeloff_flags is a linux specific variant of sctp_peeloff.  While it will compile on other systems,
       its use will result in an error return.  Portable code should use sctp_peeloff.

       On success, the new socket descriptor representing the branched-off asociation is returned.  On error, -1
       is returned, and errno is set appropriately.
