how safe is a tcp connection

[csiz]

I have a few questions:
Is the tcp connection thread safe? I may do tcp.send(packet); from more than one thread but I still want the packets to be sent whole and in order

Are the data passing through it certain? If I send 1000000 times the number 0 will it be received every time 0?

I don't know, I guess you have to read the documentation of the low-level sockets functions. But if you're talking about "order", I guess it means that your threads never try to send messages at the same time? So you shouldn't have any problem.

Yes.

Hmm about the second one, I don't know if it was my fault but my program was blocking (seg fault) and when I checked the data I was receiving there was a 76 received that should have been 0 1 or 2.

I'll investigate that further...
