Global variables

[Primrose.Mbanefo@Infineon.com]

Hello,

I'm trying to extract global variables from a set of c++ files. I tried
using:
cp_namespace_decls(global_namespace);

But this returns a whole set of variables which I do not want to know
about now (i.e stdout, timezone, _ZTISt10ostrstream e.t.c)

How do I get rid of this excess or what is the right way of accessing
such variables?

Thanks,
Primrose
