information elements: * * When a field extends over more than one octet, the order of bit * values progressively decreases as the octet number increases. * The least significant bit of the field is represented by the * lowest numbered bit of the highest numbered octet of the field. * * which sure sounds little-endian. * * [ * Later comment: * Actually: To me. the above reads as being BIG_ENDIAN. * IOW: if bytes are numbered from 0 to n, then the n'th byte * ("highest numbered octet") has the least significant bit. * ] * * However, for some not-entirely-obvious reason, BSSGP_LITTLE_ENDIAN, which * was passed to proto_tree_add_item() as the byte-order argument, was * defined as FALSE - which meant big-endian. * * For now, we'll use ENC_BIG_ENDIAN, now that we have ENC_BIG_ENDIAN and * REP_LITTLE_ENDIAN definitions. */ #define BSSGP_SEP ", " void proto_register_bssgp(void); void proto_reg_handoff_bssgp(void); static guint8 g_pdu_type, g_rim_application_identity; static guint32
