[gameprogrammer] Re: recvfrom returning 0 on UDP and blocking

Assuming this is th same function:

Upon successful completion, recvfrom() returns the length of the message
in bytes. If no messages are available to be received and the peer has
performed an orderly shutdown, recvfrom() returns 0. Otherwise the
function returns -1 and sets errno to indicate the error.
