Resolve

名称

   resolve() - resolve an internet address to domain name, or vice versa

语法

   int resolve( string address, string | function callback_func );

描述

   resolve()  resolves  'address',  which should be an internet address in the form "127.0.0.1" or a domain name, into its domain name, or  internet  address.   When  the  resolve is complete, 'callback_func' will be called in the current object.  The form of the callback is:

   void callback(string address, string resolved, int key);

   'key' will match  up  with  the  number  that  the  call  to  resolve() returned.   'address'  will  be  the  domain  name  of  the  host,  and 'resolved' the dotted decimal ip address.  The unknown value will be  0 if the lookup failed.
