       lc_channel_oti_peek - peek at OTI header

LIBRARY

       Librecast library (liblibrecast, -llibrecast)

SYNOPSIS

       #include <librecast/net.h>

       int lc_channel_oti_peek(lc_channel_t *chan, rq_oti_t *oti, rq_scheme_t *scheme);

       Compile and link with -llibrecast.

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.

RETURN VALUE

       lc_channel_oti_peek()  returns zero on success. On error, -1 is returned, and errno is set
       to indicate the 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)
