-This blocking function moves one ''raw'' packet from a kernel buffer to an user buffer defined by the <buffer> argument. The <length> argument define the user buffer size (in bytes). Packets exceeding this size are discarded. Only packets matching the local IP address and local port number, defined by the <socket> argument will be delivered (2 matching conditions). If the socket is in ''connected'' mode, the matching must also be on remote IP address an remote port number (4 matching conditions). The received packet length is written in the <addr_len> argument. The remote socket address is written in the <dest_addr> argument. It returns only when the user buffer has been written. The user thread blocking uses a descheduling policy.
