What happens if signal interrupts sendto or recvfrom call on datagram socket? Can I expect that these calls always return -1 with errno == EINTR or they can return positive number of bytes, but I shall repeat the call entirely?

On a datagram socket,
sendtoandrecvfromalways send and receive complete datagrams, or nothing at all. If they could stop in the middle of a datagram that would defeat the point of datagrams.There is an exception -
recvfrommight cut off the end of a datagram if the buffer is too small. The entire datagram is received, but your program doesn't get to see all of it.
