Try something like:

strcpy(un.sun_path, "(/tmp/mapping-foo");
fd=socket(AF_UNIX,SOCK_STREAM,0);

SCTP_PEELOFF(3) 					     Linux Programmer's Manual						   SCTP_PEELOFF(3)

NAME
sctp_peeloff - Branch off an association into a separate socket. SYNOPSIS
#include <sys/types.h> #include <sys/socket.h> #include <netinet/sctp.h> int sctp_peeloff(int sd, sctp_assoc_t assoc_id); DESCRIPTION
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. RETURN VALUE
On success, the new socket descriptor representing the branched-off asociation is returned. On error, -1 is returned, and errno is set appropriately. ERRORS
EBADF sd 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. SEE ALSO
