perl module to write on a var

[Larry]

Hi,

I've been using a perl module that writes binary data on a file...now
I would like to save this binary data on a var insted of on a file...the
following si the code:

my $_mp3 = MP3::Tag->new($file);

my $_id3v2 = $_mp3->new_tag("ID3v2");
$_id3v2->add_frame($key, $value);
$_id3v2->write_tag();

I'd rather save the data on a var kept in memory (I must not save the
data on a file!)

so is there anyway to have my $_mp3 = MP3::Tag->new($file); point to a
var?

thanks

Unfortunately you don't have much control with MP3 module, so you'd
have to write the file first and then read it into a variable.

Probably not unless MP3::Tags'
docs hint otherwise. To be sure, you might want to look inside
the constructor itself:

perldoc -m MP3::Tag | perl -ne 'print if /^sub new/../^}/'

The constructor hints that you can't, but it isn't exactly clear. All it
does is stuff the name into a hash. The actual open of any filehandle
based on the name passed to the constructor seems to be delegated 8 ways
from Sunday.

If the MP3::Tag docs don't provide any hints, you can usually peek at
the constructor to see what's
possible:

perldoc -m MP3::Tag |
perl -ne'print if /^sub new/../^}/'
