The media_get_attr function fetches the
specified result (attribute) of the media file named in the filename
parameter. This is the filename provided by a previously run call
to media scan to perform the actual scan itself. A number of different
media scans can be queried at the same time so long as they do not have
the same file name. The results are all obtained and stored during the
media_scan call and are simply retrieved from a results array when
using media_get_attr.
