SYNTAX

#include <socket.h>

int socket_udp4();

DESCRIPTION

socket_udp4 creates a non-blocking UDP/IP datagram socket and returns a file descriptor pointing to that socket. If something goes wrong, socket_udp4 returns -1, setting errno appropriately, without allocating any resources.

EXAMPLE

  #include <socket.h>

  int s;
  char ip[4];
  uint16 p;

  s = socket_udp4();
  socket_bind4(s,ip,p);
  socket_connect4(s,ip,p);
