Where is the implementation of "getaddrinfo" called by InetAddress.java

I have been recently studying on why the Browser in the android OS does not support accessing IPv6 websites through IPv6 URLs and I think it is due to the native method getaddrinfo called by android/dalvik/libcore/luni/src/main/java/java/net/ InetAddress.java which is then called by the Browser application throws an UnknownHostException when trying to convert an IPv6 URL to its addresses.

Begin from line 507, the code of InetAddress.java is:

try {   
    InetAddress[] addresses = bytesToInetAddresses(getaddrinfo(host), host);   
    addressCache.put(host, addresses);   
    return addresses;

and the native method is declared at line 516 as:

private static native byte[][] getaddrinfo(String name) 
        throws UnknownHostException; 

But I haven't found any hint about where the implementation of this native method getaddrinfo is although I found there are two files named getaddrinfo.c开发者_Python百科. Does here follow the rules of JNI or NDK? If so, a statement of System.loadLibary("NameOfTheLibrary") should be found but I didn't find it.

Any one could give me a hint on finding the implementation of this native method getaddrinfo?

The complete source file of InetAddress.java can be found at http://ooowjc.wikispaces.com/Attachments

In the Android source tree, libcore/luni/src/main/native/java_net_InetAddress.cpp.

I'd include a link to the file in the android-git repository, but the site seems to be hosed at the moment.
