◆ calcChecksum()
| boost::uint16_t senf::UDPPacketParser::calcChecksum | ( | ) | const |
calculate (pseudo-)header checksum
calculate and return the checksum of the (pseudo-)header
- See also
- 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

inline |
validate header checksum
return true if the checksum field is equal to the calculated checksum
