sctp_optinfo - Get options on a SCTP socket.

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.
