int sctp_opt_info(int sd, sctp_assoc_t id, int opt,
                  void * arg, socklen_t * size);


sctp_opt_info is a wrapper library function that can be used to get SCTP level options on a socket. sd is the socket descriptor for which the option is requested. For one-to-many style sockets, id specifies the association to query. For one-to-one style sockets, id is ignored. opt specifes the SCTP socket option to get. arg is an option-specific structure buffer provided by the caller. size is a value-result parameter, initially containing the size of the buffer pointed to by arg and modifed on return to indicate the actual size of the value returned.


On success, sctp_opt_info returns 0 and on failure -1 is returned with errno set to the appropriate error code.
