NAME

IO::File::WithFilename - filehandles that know their origin

SYNOPSIS

    use IO::File::WithFilename;

    my $fh = IO::File::WithFilename->new('../movies/kin-dza-dza.ogg', O_RDONLY);
    print $fh->filename, "\n";
    print "$fh\n"; # same as above

DESCRIPTION

This module does everything that IO::File does, but implements filename method, that File::Temp objects have. It lets you write the code that is ignorant of what classes of objects it works with.

If you want to check if it is safe to call filename method, you are recommended to call can method rather than to check an object's inheritance:

    print $obj->filename, "\n" if eval { $obj->can('filename') };

EXPORT

Same as IO::File, i. e. O_XXX constants from the Fcntl module (if this module is available).
