resolv.conf equivalent on Cygwin

[Hiroki Sakagami]

Hi,

I am trying to port a program with an asynchronous DNS resolver to
Cygwin.  Because it can't use gethostbyname() family functions, it
needs to read /etc/resolv.conf file.  However, Windows seems to have
the names of DNS servers in the registry key
"SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces" or
something.  Is there any Cygwin standard way to query DNS server
names?

I already wrote the code which use RegOpenKeyEx() and other functions.
 But if there is another appropriate way I'd like to use it.

Regards,
