NAME

       lc_ctx_coding_set, lc_channel_rq_overhead - set Librecast RaptorQ overhead packets

LIBRARY

       Librecast library (liblibrecast, -llibrecast)

SYNOPSIS

       #include <librecast/net.h>

       int lc_ctx_rq_overhead(lc_ctx_t *ctx, int overhead);
       int lc_channel_rq_overhead(lc_channel_t *chan, int overhead);

       Compile and link with -llibrecast.

DESCRIPTION

       lc_ctx_rq_overhead()  sets  the  default overhead packets for channels subsequently created using context
       ctx.

       lc_channel_rq_overhead() sets RaptorQ overhead packets for a  Librecast  channel,  chan,  overriding  any
       defaults inherited from the parent Librecast context.

       chan is a pointer to a Librecast channel.

       The overhead argument is the number of overhead packets to send in a single call to lc_channel_send(3) or
       lc_channel_sendmsg(3)  .   If  >= 0, a single call to a sending function with LC_CODE_FEC_RQ enabled will
       cause K' + overhead packets to be sent.

       If < 0, no automatic sending will occur.

RETURN VALUE

       Returns the new overhead value.

ERRORS

       None.
