PerfPkt6 (DHCPv6 packet)
Definition: perf_pkt6.h:41
boost::shared_ptr< PerfPkt6 > PerfPkt6Ptr
Definition: perf_pkt6.h:127
OptionBuffer data_
Unparsed data (in received packets).
Definition: pkt.h:334
size_t getTransidOffset() const
Returns transaction id offset in packet buffer.
Definition: perf_pkt6.h:71
bool rawPack()
Prepares on-wire format from raw buffer.
Definition: perf_pkt6.cc:35
Represents a DHCPv6 packet.
Definition: pkt6.h:44
PerfPkt6(const uint8_t *buf, size_t len, size_t transid_offset=1, uint32_t transid=0)
Constructor, used to create messages from packet template files.
Definition: perf_pkt6.cc:25
virtual size_t len()
Returns length of the packet.
Definition: pkt6.cc:63
