[Ethernet]
描述
Write data to all the clients connected to a server. This data is sent as a byte or series of bytes.
語法
// telnet defaults to port EthernetServer server = EthernetServer(int); server.write(val) server.write(buf, len)
參數
val: a value to send as a single byte (byte or char)buf: an array to send as a series of bytes (byte or char)len: the length of the buffer
回傳
byte (write() returns the number of bytes written. It is not necessary to read this.)
範例
#include <Ethernet.h>
// network configuration. gateway and subnet are optional.
byte mac[] = { 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 };
//the IP address:
byte ip[] = { 10, 0, 0, 177 };
// the router's gateway address:
byte gateway[] = { 10, 0, 0, 1 };
// the subnet:
byte subnet[] = { 255, 255, 0, 0 };
// telnet defaults to port 23
EthernetServer server = EthernetServer(23);
void setup()
{
// initialize the ethernet device
Ethernet.begin(mac, ip, gateway, subnet);
// start listening for clients
server.begin();
}
void loop()
{
// if an incoming client connects, there will be bytes available to read:
EthernetClient client = server.available();
if (client == true) {
// read bytes from the incoming client and write them back
// to any clients connected to the server:
server.write(client.read());
}
