My (partially working) iteration code looks like: /* Start counting from 13 */ for (rwe_pos = 13; rwe_pos < tvb_get_guint8(tvb, 13); rwe_pos++) { proto_tree_add_item(felica_tree, hf_felica_block_nbr, tvb, rwe_pos + 1, 1, ENC_BIG_ENDIAN); }
How about something like this: /* Start counting from 14 */ for (rwe_pos = 14; rwe_pos < tvb_get_guint8(tvb, 12); rwe_pos+=2) { proto_tree_add_item(felica_tree, hf_felica_block_nbr, tvb, rwe_pos, 1, ENC_BIG_ENDIAN); } ... or if you want the 0x80 byte highlighted as part of the block number (instead of skipping it), then do something like: /* Start counting from 13 */ for (rwe_pos = 13; rwe_pos < tvb_get_guint8(tvb, 12); rwe_pos+=2) { proto_tree_add_uint(felica_tree, hf_felica_block_nbr, tvb, rwe_pos, 2, tvb_get_guint8(tvb, rwe_pos + 1)); } - Chris ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
