matching function for ipfx in gcc 3.4.2

[anandi.thirunavukkarasu@wipro.com]

I have moved to gcc version 3.4.2(linux sll) So I am migrating a
component to this version from gcc 2.96.

In my existing code I am using the *ipfx* function of the istream
present in the iostream.h file.
 
But I can't find this function in this version of gcc 3.4.2. Its giving
the following error.

error: 'struct std::basic_istream<char, std::char_traits<char> >' has no
member named 'ipfx'

Can u help me in finding a matching function in this version?

Regards,
Anandi
