A datagram socket (type SOCK_DGRAM)
supports bidirectional flow of
data in the datagram model of the network level protocol.
Record boundaries are preserved.
Since the transport layer is unreliable, the processes
themselves must be responsible for reliability assurance.
For example, the receiving process may need to perform resequencing and
elimination of duplicates.
The datagram socket can be used in applications where reliability of
an individual packet is not essential, for example, in
broadcasting messages for the purpose of updating a status table.
