recvfrom returns 0 question

Hello,
I am using 'recvfrom' to read from RTP media stream in streaming player app.
I see that recvfrom occasionally returns '0'. It's easy to get around the issue but I wonder what might be a cause for it in the first place... Isn't
'recvfrom' blocking call? Any ideas ?
Thanks,

The return value of zero indicates that a graceful shutdown has occurred, in relation to the blocking call question it depends on the options set for the socket.

Yes, I saw man page for recvfrom... The point is: there's no logic to explicitly shutdown the socket, so I wondered why it might happen in the "midstream"...
Thank you,
