iostream.h vs iostream (the old and new functions)

[lucky6969b]

I am trying to port an old application from unix to win32.
The program was called C++ Sim
In that program, it uses iostream.h extensively which doesn't conform to
the new C++ standard library.
The functions that I found no longer supported are
1) setb()
2) base()
3) allocate()
4) ebuf()
and so on.
What is the quickest way to convert all these calls and make them conform to the new C++ standard library?
Thanks
Jack

Understand the code and then write the (near) equivalent code using the standard library (or other libraries, if necessary).

Some of these are documented on MSDN (eg setb and ebuf). Search on http://msdn.microsoft.com/en-US/#fbid=xs73WvvEHZg

I see. But those functions are not supported by the 7.0a SDK.
They are only available with Visual C++ 6.0.

which turns out to be quite hairy.
Where can I find a mapping table for legacy names and the new names for these changes?
Thanks

Yes, but at least you will have an idea from the documentation as to their function.

I doubt there is one as it's not just name changes from unix legacy to ansi c++ but functionality as well as per laserlight's post #2.

Okay, I tried to exclude that file because nobody was using it, it compiles now,
thanks

Hello folks,
I have narrowed down from about 30 compilation errors to 1 compilation error which relates to
the unix task.h header file. I sort of google and cannot find good info on it.
