71 * Per-Packet Information (PPI) header.
72 * See the PPI Packet Header documentation at http://www.cacetech.com/documents
77 * PPI headers have the following format:
79 * ,---------------------------------------------------------.
80 * | PPH | PFH 1 | Field data 1 | PFH 2 | Field data 2 | ... |
81 * `---------------------------------------------------------'
83 * The PPH struct has the following format:
85 * typedef struct ppi_packetheader {
86 * guint8 pph_version; // Version. Currently 0
87 * guint8 pph_flags; // Flags.
88 * guint16 pph_len; // Length of entire message, including this header and TLV payload.
89 * guint32 pph_dlt; // libpcap Data Link Type of the captured packet data.
90 * } ppi_packetheader_t;
92 * The PFH struct has the following format:
94 * typedef struct ppi_fieldheader {
95 * guint16 pfh_type; // Type
96 * guint16 pfh_datalen; // Length of data
97 * } ppi_fieldheader_t;
99 * Anyone looking to add their own PPI dissector would probably do well to imitate the GPS
100 * ones seperation into a distinct file. Here is a step by step guide:
101 * 1) add the number you received to the enum ppi_field_type declaration.
102 * 2) Add a value string for your number into vs_ppi_field_type
103 * 3) declare a dissector handle by the ppi_gps_handle, and initialize it inside proto_reg_handoff
104 * 4) add case inside dissect_ppi to call your new handle.
105 * 5) Write your parser, and get it loaded.
106 * Following these steps will result in less churn inside the ppi proper parser, and avoid namespace issues.
