espconn_gethostbyname

[IPQ]

Hello,

I'm using RTOS 1.4 and I have a question about espconn_gethostbyname...

What's the third parameter and what is it used for?

espconn_gethostbyname(&user_tcp_conn, NET_DOMAIN, &tcp_server_ip, user_dns_found);

Thank you in advance

Hi,

The third parameter can be used to store the IP address which got by DNS, so that if users call espconn_gethostbyname again, it won't run DNS again, but just use the IP address it already got.

Thanks for your interest in ESP8266 !
