From what I know, using send and recv, they are sometimes that
not all parts of data are sent and receive at once. I wonder if
this is also the case for datagram sendto and recvfrom?

Thanks

Datagrams always send and receive the whole datagram.  The only 
exception is if the receive buffer is too small for the datagram.  On 
some systems the excess is discarded, on others it will be retained for 
the next recv or recvfrom to read.
