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.
