How to extract size of a packet?

[Koo]

Look at this example...

SOCKET s;

//you bind and stuff...
//then you recive a paket.

Is there a smart, secure way to get the size of the paket, allocate a
matching buffert and then load the data into it?

I believe that you're in a wrong newsgroup. C++ does not, never
did, and, hopefully, never will, have any support for networking.
There are libraries for that, they are platform-specific. You
need to ask in a newsgroup dedicated to your platform.
