ping()
Açıklama
Ağdaki uzak bir aygıta ping atın.
Sözdizimi
(İp) grps.ping;
grps.begin (ip, ttl);
grps.begin (ana bilgisayar);
grps.begin (ana bilgisayar, ttl);
Parametreler
ip : ping yapılacak IP adresi (4 baytlık dizi)
host : ping yapılacak ana bilgisayar (dize)
ttl : Yaşam süresi (isteğe bağlı, varsayılan 128'dir). İsteğin yönlendirilebileceği maksimum yönlendirici sayısı.
İadeler
- Hedef (IP veya ana bilgisayara erişilemiyorsa) GPRS_PING_DEST_UNREACHABLE
- Ping zaman aşımına uğradığında GPRS_PING_TIMEOUT
- Ana bilgisayar çözümlenemediğinde GPRS_PING_UNKNOWN_HOST
- Bir hata oluştuğunda GPRS_PING_ERROR
