Answer 1

Using python you can easily read/edit a torrent file using bencode.py module

Example:

>>> import bencode
>>> rawdata = open('foo.torrent').read()
>>> bencode.bdecode(rawdata)
{'announce': 'http://cbbatracker.appspot.com/announce',
 'comment': 'HOTD for testing purposes',
 'created by': 'Transmission/2.04 (11151)',
 'creation date': 1292094068,
 'encoding': 'UTF-8',
 'info': {'length': 262212441,
          'name': '[SnF] Highschool of the Dead 02 [285FB2DA].mp4',
          'piece length': 131072,
          'pieces': '...lot of binary data...',
          'private': 0}}

Answer 2

yes it's possible. Lot of open source torrent softwares use the libtorrent library. It's available in C++ langage

libtorrent

Answer 3

You have to be more specific what you actually mean. If you meant "info.name" from the metafile, then any bencode module for any language makes that rather easy.
