如题所示，代码如下：
void TCP_Test(void *arg)
{
struct netconn *conn;
struct netbuf *UDPNetbuf;
struct ip_addr destip; //目标机IP //static
unsigned short destport; //目标机端口号 //static
unsigned char Text[]="hello i am udp";
destip.addr = htonl(0xC0A80164); //192.168.1.100
destport=1026;
conn = netconn_new(NETCONN_UDP); //创建UDP连接
netconn_bind(conn,&IP_ADDR_ANY,80); //绑定端口号
while(1)
{
netconn_connect(conn,&destip,destport); // 连接远程主机 //
UDPNetbuf= netbuf_new(); // 建立一个新的netbuf //
netbuf_ref(UDPNetbuf,Text,sizeof(Text)); // 引用这个文本给netbuf //
netconn_send(conn,UDPNetbuf); // 发送文本 //
netconn_delete(conn); // 删除conn和buf //
netbuf_delete(UDPNetbuf); //释放缓冲区//
}
}
