lc_ctx_coding_set() sets the default encoding options for sockets and channels subsequently created using
context ctx.
lc_channel_coding_set() sets encoding options for a Librecast channel, chan, overriding any defaults
inherited from the parent Librecast context.
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.
