169 The <B>SilcPacket</B> is returned by the packet engine in the SilcPacketReceive
170 callback. The application can parse the data payload from the
171 <B>SilcPacket</B>. Also packet type, flags, and sender and destination
172 IDs are available. The application must free the packet with the
173 <A HREF="silcpacket-silc_packet_free.html">silc_packet_free</A> function if it takes it in for processing.
175 The `buffer' field contains the parsed packet payload and the start
176 of the data area will point to the start of the packet payload.
178 The list pointer `next' can be used by the application to put the
179 packet context in a list during processing, if needed.
