Member Function Documentation

boost::uint16_t senf::UDPPacketParser::
calcChecksum ()

calculate (pseudo-)header checksum

calculate and return the checksum of the (pseudo-)header

senf::IpChecksum
Fix:
What about a hop-by-hop routing option? Which destination is used in IPv4 ?
Fix:
May there be another header between the IPv4 header and UDP? if so, we need to hack the correct protocol number here ...
Todo:
Implement routing header support
