win32 (net-receive-udp)

Hello Lutz,
Im wondering how (net-receive-udp) is used under windows.
As it states in the manual and works pratical that (net-receive-udp) under
windows must have the EXACT amount of bytes it should receive or otherwise it returns "nil".
Actualy that is true on protocol base like Tftp. But plain udp
you never know how big the packets size will be.
So how can the net-receive-udp know how big the size of the packet is
that is coming in?
If i create a simple UDP server under windows in C then i can receive
all kinds of data packages. So my question, is this packetsize receive on Windows a windows or a newlisp behaviour?
