available()

Description

Returns the number of bytes available for reading (that is, the amount of data that has been written to the client by the server it is connected to).

available() inherits from the Stream utility class.

Syntax


client.available()

Parameters

none

Returns

The number of bytes available.

Example

#include <Ethernet.h>

byte ip[] = { 10, 0, 0, 177 };
byte server[] = { 64, 233, 187, 99 }; // Google

EthernetClient client;

void setup()
{
  Ethernet.begin(NULL, ip);
  Serial.begin(9600);

  delay(1000);

  Serial.println("connecting...");

  if (client.connect(server, 80)) {
    Serial.println("connected");
    client.println("GET /search?q=arduino HTTP/1.0");
    client.println();
  } else {
    Serial.println("connection failed");
  }
}

void loop()
{
  if (client.available()) {
    char c = client.read();
    Serial.print(c);
  }

  if (!client.connected()) {
    Serial.println();
    Serial.println("disconnecting.");
    client.stop();
    for(;;)
      ;
  }
}
