NAME
       UDP - Communications Protocol Internet User Datagram Protocol

SYNOPSIS
       #include <sys/socket.h>
       #include <netinet/udp.h>

       This is an example of how you would create an endpoint for the UDP
       connection:

           s = socket(AFINET, SOCKDGRAM, 0);

DESCRIPTION
       UDP is a simple, unreliable datagram protocol that is used to support
       the SOCK_DGRAM abstraction for the Internet protocol family.

       UDP sockets are connectionless, and are normally used with the
       sendto(2) and recvfrom(2) calls.  The connect(2) and bind(2) calls
       may also be used to fix the destination for future packets (in which
       case the recv(2) or read(2) and send(2) or write(2) system calls may
       be used).  Listen(2) and accept(2) are not valid operations on
       datagram sockets.

SEE ALSO
       send(2), recv(2), sendto(2), recvfrom(2).
