facing problem with gethostbyname2

[sonal kamra]

Hi, 
 
I am using Bind 9.2.3 resolver library, I am facing some problem with
gethostbyname2(), i am not able to get IPv4-mapped-IPv6 address.
Where  /etc/resolv.conf look like this
================================
domain myzone.com
nameserver 10.53.1.1
options inet6
================================
gethostbyname2() is working fine when i am giving the hostname that have
ipv6 address where family parameter in gethostbyname2 is AF_INET6.
But for the hostname that is having only IPv4 address, where family
parameter in the gethostbyname2 is AF_INET, according to the man page 
it should return IPv4-mapped-IPv6 address, but gethostbyname2 is returning
IPv4 address where it should return IPv4-mapped-IPv6 address.
 
Is there any option other than inet6 in the resolv.conf that we have to set
to get IPv4-mapped- IPv6 address.
If anyone has face this issue then please tell me.
 
Thanks & Regards,
Sonal
