socket_send4 - send a UDP datagram
#include <socket.h> ssize_t socket_send4(int s, const char* buf, size_t len, const char ip,uint16 port);
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.
socket_send4 returns 0 if the datagram was sent successfully. If not, it returns -1 and sets errno appropriately.
#include <socket.h> int s; char ip; uint16 p; s = socket_tcp4(); socket_bind4(s,ip,p); socket_send4(s,"hello, world",12,ip,p);
