Hello, I have a question regarding to register a boolean field, especially about the FIELDBASE value.
In README.developer it says the general rules: static hf_register_info hf[] = { { &hf_PROTOABBREV_FIELDABBREV, { "FIELDNAME", "PROTOABBREV.FIELDABBREV", FIELDTYPE, FIELDBASE, FIELDCONVERT, BITMASK, "FIELDDESCR", HFILL } } }; FIELDBASE BASE_NONE, BASE_DEC, BASE_HEX, BASE_OCT, BASE_DEC_HEX, BASE_HEX_DEC, or BASE_CUSTOM, possibly ORed with BASE_RANGE_STRING In proto.h the FIELDBASE declared as enum: typedef enum { BASE_NONE, /**< none */ BASE_DEC, /**< decimal */ BASE_HEX, /**< hexadecimal */ BASE_OCT, /**< octal */ BASE_DEC_HEX, /**< decimal (hexadecimal) */ BASE_HEX_DEC, /**< hexadecimal (decimal) */ BASE_CUSTOM /**< call custom routine (in ->strings) to format */ } base_display_e; But checking some examples of packet-gtp.c: {&hf_gtp_flags_e, {"Is Next Extension Header present?", "gtp.flags.e", FT_BOOLEAN, 8, TFS(&yes_no_tfs), GTP_E_MASK, "Is Next Extension Header present? (1 = yes, 0 = no)", HFILL}}, {&hf_gtp_ms_valid, {"MS validated", "gtp.ms_valid", FT_BOOLEAN, BASE_NONE, NULL, 0, "MS validated", HFILL}}, {&hf_gtp_cmn_flg_ppc, {"Prohibit Payload Compression", "gtp.cmn_flg.ppc", FT_BOOLEAN, 8, NULL, 0x01, "Prohibit Payload Compression", HFILL}}, It is not clear. As FIELDBASE it uses BASE_NONE or 8. Why? What is 8? Do I have to use BASE_NONE in case of no value string table (NULL) and 0 (default) mask? Do I have to use 8 if I have a value string table and or a non-zero mask? Can sombeody explain this to me please?
