Send bytes on TCP connection

[nickbelvedere 0]

Hello guys,

how can I send bytes on a TCP connection? I had success sending strings, but I'm interested in sending some bytes down the line.

 

Thanks!

You could try using the serialization api.

You're going to want to do write the bytes to the stream using string.char

 

As an example, you can look at a program I made a while ago (it's slow from what I recall, but I was just testing stuff). http://pastebin.com/NLvQmUYh

In Lua, strings are just bytes. There is no distinction between text and raw data (like in Java or Python), instead all characters represent their ASCII byte value. (Well, Lua makes no promises about which character set is actually used, but in almost all cases it's ASCII or a superset of it, like Latin-1.) Unicode characters are represented by UTF-8 byte sequences, there is no native Unicode support in Lua, except for the utf8 library that provides a few utilities for encoding and decoding UTF-8 strings.
