param verification: is a handle?

[A. Sicken]

Hello,

I have to handle follwing problem: A class method can be called with an
argument, which can be
a) a simple filename
b) a glob (perls default file handles)
c) a reference to a glob (IO::Handle object for example)

How do I verify the argument? Or where can I find an example how to do
it?

In advance, thanx

The 'openhandle' function in Scalar::Util should do this nicely.

Thank, you - that's it!
