************************************************************************
36
* The motivation for this wrapper is to avoid issues where you need to
37
* decode both FLAC and Ogg FLAC but don't want to enclose all of your code
38
* in enormous if blocks where the body of the two branches is essentially
39
* the same. For example, you don't want to do something like this:
43
* OggFLAC__blah_blah();
44
* OggFLAC__more_stuff();
52
* when you really just want this:
54
* EasyFLAC__blah_blah();
55
* EasyFLAC__more_stuff();
57
* This is even more cumbersome when you have to deal with constants.
59
* EasyFLAC uses essentially the same API as
60
* FLAC__stream_decoder with two additions:
62
* - EasyFLAC__is_oggflac() for those rare occassions when you might
63
* need to distiguish the difference cases.
65
* - EasyFLAC__stream_decoder_new() takes a parameter to select when
66
* you are reading FLAC or Ogg FLAC.
68
* The constants are all FLAC__stream_decoder_*.
70
* WARNING: Always call EasyFLAC__set_client_data() even if all you
71
* want to do is set the client data to NULL.
