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