Example

SYNTAX

#include <socket.h>

ssize_t socket_send4(int s, const char* buf, size_t len,
const char ip[4],uint16 port);

DESCRIPTION

socket_send4 sends len bytes starting at buf in a UDP datagram over the socket s to UDP port port on IP address ip.

You can call socket_send4 without calling socket_bind4. This has the effect as first calling socket_bind4 with IP address 0.0.0.0 and port 0.

RETURN VALUE

socket_send4 returns 0 if the datagram was sent successfully. If not, it returns -1 and sets errno appropriately.

EXAMPLE

#include <socket.h>

int s;
char ip[4];
uint16 p;

s = socket_tcp4();
socket_bind4(s,ip,p);
socket_send4(s,"hello, world",12,ip,p);
