recvfrom() function receives a message from connectionless-mode socket.
It also permits the application to retrieve the source address of received data.
buf_ | points to buffer where the message should be stored |
size_ | buffer length is bytes |
peer_addr_ | pointer to the address structure where sending address is to be stored |
