I'm making a dissector for a protocol that is based on UDP. I'd like to show
the source and destination ports in the Info column, pretty much the same way as it shown by the UDP dissector. Can somebody suggest how to get the port numbers when I'm dissecting the payload? If you want to leave the column information supplied by the UDP dissector alone, you can either call col_set_fence(pinfo->cinfo, COL_INFO) before adding or setting your own column information, or you can avoid column adds/sets and use col_append_*() functions instead. If you really need access to the UDP ports though, you can get them from pinfo->srcport and pinfo->destport. ___________________________________________________________________________ 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
