    if (err !== null) {
        console.log(hash);
    }
});

Provide a file:

ed2k.ed2k_hash_for_filepath('/path/to/file', function(err, hash) {
    if (err !== null) {
        console.log(hash);
    }
});

Methods

stream - stream (http://nodejs.org/api/stream.html)

callback - function(err, ed2k_uri)

    err - null if success, !null if error, passed from fs modules

    ed2k_uri - String if success, undefined if err

ed2k_hash_for_filepath(path, callback)

path - String, relative or absolute path to a file

callback - function(err, ed2k_uri)

    err - null if success, !null if error, passed from fs modules

    ed2k_uri - String if success, undefined if err

ed2k_uri_for_hash(hash, filename, size)

hash - String, string hash of file

filename - String, name of file, path not required

size - String/Int, size of file

returns: String, ed2k uri

ed2k_uri_for_filepath(path, callback)

path - String, relative or absolute path to a file

callback - function(err, ed2k_uri)

    err - null if success, !null if error, passed from fs modules

    ed2k_uri - String if success, undefined if err
