bpf_u_int32 bpf_hdr::bh_caplen

Definition at line 152 of file Bpf.h.

UINT bpf_hdr::bh_caplen

Length of captured portion. The captured portion can be different from the original packet, because it is possible (with a proper filter) to instruct the driver to capture only a portion of the packets. Definition at line 169 of file Packet32.h.

bpf_u_int32 bpf_hdr::bh_datalen

Definition at line 153 of file Bpf.h.

UINT bpf_hdr::bh_datalen

Original length of packet. Definition at line 172 of file Packet32.h.

u_short bpf_hdr::bh_hdrlen

Definition at line 154 of file Bpf.h.

USHORT bpf_hdr::bh_hdrlen

Length of bpf header (this struct plus alignment padding). In some cases, a padding could be added between the end of this structure and the packet data for performance reasons. This filed can be used to retrieve the actual data of the packet. Definition at line 173 of file Packet32.h.

struct timeval bpf_hdr::bh_tstamp

It is stored in a TimeVal structure. The timestamp associated with the captured packet. Definition at line 167 of file Packet32.h.

struct timeval bpf_hdr::bh_tstamp

Definition at line 151 of file Bpf.h.

struct timeval bpf_hdr::bh_tstamp

It is stored in a TimeVal structure. The timestamp associated with the captured packet. Definition at line 135 of file PACKET32.H.
