IO::File::WithFilename(3pm) User Contributed Perl Documentation IO::File::WithFilename(3pm)

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).
