socket_send4(3)socket_send4(3)NAMEsocket_send4 - send a UDP datagram
SYNTAX
#include <socket.h>
ssize_t socket_send4(int s, const char* buf, size_t len,
const char ip[4],uint16 port);
DESCRIPTIONsocket_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 VALUEsocket_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);
