Structure SilcPacketContext NAME
        typedef struct { ... } SilcPacketContext;
DESCRIPTION
        In packet sending this is filled and sent to silc_packet_assemble
        which then uses it to assemble new packet. In packet reception pointer
        to this context is sent to silc_packet_parse which parses the packet
        and returns the relevant information to this structure. On packet
        reception returned ID's are always the hash values of the ID's from
        the packet.

        Short description of the fields following:

        SilcUInt16 truelen

          True length of the packet.  This may be set by the caller before
          calling any of the silc_packet_* routines.  If not provided the
          library will calculate the values.

        SilcPacketFlags flags

          Packet flags. Flags are defined above.

        SilcPacketType type

          Type of the packet. Types are defined below.

        unsigned char *src_id
        SilcUInt8 src_id_len
        SilcUInt8 src_id_type

          Source ID, its length and type. On packet reception retuned ID's
          are always the hash values of the ID's from the packet.

        unsigned char *dst_id;
        SilcUInt8 dst_id_len;
        SilcUInt8 src_id_type;

          Destination ID, its length and type. On packet reception retuned
          ID's are always the hash values of the ID's from the packet.

        bool long_pad

          If set to TRUE the packet will include the maximum padding allowed
          in SILC packet, which is 128 bytes.  If FALSE only the amount of
          padding needed will be applied.

        SilcUInt16 users;

          Reference counter for this context. The context is freed only
          after the reference counter hits zero. The counter is added
          calling silc_packet_context_dup and decreased by calling the
          silc_packet_context_free.

        SilcUInt8 padlen

          The padded length of the packet.  This may be set by the caller
          before calling any of the silc_packet_* routines. If not provided
          the library will calculate the values.

        SilcUInt32 sequence;

          Packet sequence number.  Set only when this context is a parsed
          packet.

        SilcBuffer buffer

          The actual packet data.  Set only when this context is a parsed
          packet.
