DESCRIPTION

       The  lc_channel_oti_peek()  function peeks at the OTI header (RaptorQ FEC Object Transmission Information
       header - see RFC 6330) in the next packet of the socket bound to channel chan and  sets  oti  and  scheme
       accordingly.

       error.

ERRORS

       EBADMSG
              The header is malformed, or T does not match the expected value for chan.

       errno can also be set to any of the errors returned by lc_socket_recv(3)
