Yes you’re right… and deallocation is automatic.

for such a small allocation, it’s better to allocate on the stack via alloca, at least where I come from working on game consoles

You don’t need a pointer-to-pointer since:

unsigned char *packet;
packet = new unsigned char[size+4];

should be enough… the rest of code is pretty much the same.

When using Visual Studio Express 2010 Beta 2 to compile your example Client/Server code, there is an issue with the dynamic packet array in the Net.h header file.

unsigned char packet[size+4];

needs to be changed to:

unsigned char **packet;
packet = new unsigned char*[size+4];

and in the if statement below the cast of (unsigned char) needs to be changed to (unsigned char*)

These changes need to be applied to both ReceivePacket and SendPacket functions.

Excellent articles.
I highly support this endeavor, so I donated 10 of our Canadian dollars for you to continue.

If I decide to incorporate networking into my game prototype, then your articles are definitely the resource I will be using.

yeah, I would have paid for your knowledge right now. I have tried to avoid network programming as much as I can but now its essential that I start to use it. Your articles have really brought me up to speed, thanks for sharing
