It's not entirely clear what you're asking. A Google search for sendto and EWOULDBLOCK would imply that it can be returned, yes. Any sending operation on a socket could theoretically run out of send-buffer space, which means the operating system would have to wait until such space became available, hence EWOULDBLOCK is a reasonable value to return for a non-blocking socket.
