Problems using omanip

Hi,

I am having some difficulties compiling a library written by someone else,
and was hoping someone could indicate what's wrong! I have cut the code
down to what I believe to be the relevant part. If anyone can suggest how
to make the following code compile it would be greatly appriciated.

#include <iostream>
#include <iomanip>

std::ostream& ket(std::ostream& os, char* ket_val)
{
return os << " |" << ket_val << '>';
}

std::omanip<char*> ket(char* ket_val) //Error occurs here
{
return std::omanip<char*> (ket, ket_val);
}

From the compiler (g++ 3.3.1) I get:

test.cc:9: error: syntax error before `(' token

I believe the code was supposed to compile on earlier versions of the
compiler. I have made small changes such as removing '.h' from the headers
and putting 'std::' before some classes.

Thanks in advance for any help you can give,

David

There is no template "omanip" in C++ standard library.

It doesn't make a class standard if you simply put 'std::' before it.

If you've been using some kind of library extension and want to keep
using it, please talk to GCC people. In the Standard C++ there is no
'omanip'.

Ok, if it's not standard C++ I'd probably rather not be using it anyway.
I'll probably try to replace it with my own code to do something similar.
Thanks for your help.
