sctp_peeloff − Branch off an association into a separate socket.
#include

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.
