NAME

       lc_channel_coding_set - set Librecast channel encoding options

SYNOPSIS

       #include <librecast/net.h>

       int lc_channel_coding_set(lc_channel_t *chan, int coding);

       Compile and link with -llibrecast.

DESCRIPTION

       lc_channel_coding_set()  sets encoding options for a Librecast channel.  chan is a pointer
       to a Librecast channel.

       The coding argument can include the bitwise OR of any of the following coding options:

       LC_CODE_SYMM
              Enable symmetric key encryption. Requires that a symmetric key has been assigned to
              the Channel with lc_channel_set_sym_key(3)

       LC_CODE_FEC_RQ
              Enables  RaptorQ  Forwards  Error  Correction (FEC).  Calling lc_channel_send(3) as
              normal encodes the data to be sent.  Subsequent calls to lc_channel_send() with buf
              ==  NULL  will send the next symbol/packet.  To receive, call lc_channel_coding_set
              (chan, LC_CODE_FEC_RQ) on the receiver and then lc_channel_recv().   Encodings  are
              per  channel,  not  per  socket,  so  it is necessary to use lc_channel_recv(), not
              lc_socket_recv(3).

       LC_CODE_FEC_RAND
              Requires LC_CODE_FEC_RQ.  Use random symbols instead of sequential ESIs.

RETURN VALUE

       Returns the current value of the channel coding options.

ERRORS

       None.
