Sending enum through a packet

[Strikerklm96]

Is it safe to do this?

Packet packet;
packet << static_cast<int32_t>(Protocol::Control);//Protocol is an enum class
send(packet);

I am trying to send different types of commands through the network, and i'm not sure if this is reliable.

Why wouldn't it be safe?

I thought I read somewhere that enums aren't necessarily always the same type, which made me worried that they might not cast to the same value. I was having a few problems and just wanted to eliminate that as a possibility. I think I found my actual problem though.

And I thought the following question didn't deserve a new thread: It makes sense use both UDP and TCP in the same program right? I want TCP for data that can't get lost or duplicated ect. Do I need to bind each socket to different ports so my program actually uses two ports?

Yes, but you can cast them to any interger type (that is large enough to contain all the enum constants). So there's no problem.

Yes.

Yes.
