The answer depends on the socket options. But blocking doesn't really make a lot of sense for a udp send. The function returns once the packet has been placed in the queue. The only thing that would make it block is if there wasn't enough space in the socket buffer. As it is udp the buffer empties itself quickly, there is no wait for acknowledge.
