I am subclassing the Graph::Writer module to provide output for a new graph format and must work within the confines of the following function.

sub _write_graph
{
    my $self  = shift;
    my $graph = shift;
    my $FILE  = shift;

    #while (<$FILE>)
    #{
    #}
    
    return 1;
}

The function receives a file handle (IO::File=GLOB(0x8333a68)) to a single file ($FILE). However, I need to create two output files for this graph format and thus I need to get the filename from the $FILE file handle and use this as the base name from which I can generate two new filenames and open these for output (and close $FILE). I know this is a bit of a kludge, but I'm within the confines of original function that is being overriden. How can I do this, or has anyone got a better idea how I could do it without changing the parameters accepted by the function?

Note that I need concurrent access to the two new files rather than sequential so will need two open file handles at once.

Thanks, Arun
