matching function for out_waiting in gcc 3.4.2

[anandi.thirunavukkarasu]

Hi,

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 *out_waiting* function of the struct
streambuf present in the streambuf.h file.

But I can't find this function in this version of gcc 3.4.2. so can u
help me in finding a matching function in this version.

Thanks,
Anandi
