IO::File::WithFilename - filehandles that know their origin
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
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') };
Same as "IO::File", i. e. "O_XXX" constants from the "Fcntl" module (if this module is available).
