Can I use hostname (a URL) in Socket program?

Rahul_Y · 08-02-2010, 04:19 AM

Hi,

I don't have the IP address & Port of the server but I know the hostname (URL) to establish a connection.

How can I use it to get connected to the particular host?

Regards,
Rahul.

I think

man 3 getaddrinfo

is a good start. See also http://c-ares.haxx.se/ .

Hi Sergei Steshenko,

Thanks for the reply.

Could you please give an example for getaddrinfo.

I am trying from my side too.

Rahul

The manpage has example code, doesn't it ?

FWIW, 'c-ares' is used in 'aria2': http://aria2.sourceforge.net/ - the latter uses URLs, so there is an example inside 'aria2'.
