I'm trying something like: local msgbufferarray = buffer(ofs, plen):bytes() local temparray=ByteArray.new() temparray.append(msgbufferarray:subset(0,plen)) But get the following error: Lua Error: [string "/tmp/eris.lua"]:307: bad argument #2 to 'append' (userdata expected, got no value) Thanks Didier ___________________________________________________________________________ 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-requ...@wireshark.org?subject=unsubscribe
