It is quite hard to check for all of the possible filehandles that could be passed to a function. In the Scalar::Util module there is a function called openhandle() that can be used to check whether the function argument is a valid filehandle.

As a less rigourous solution you could just use ref to check if the argument is a reference and then presume a filehandle. It will depend on your application.
