+ The general strategy of these tests (for interface levels 1 and 2) is
+ to create a dummy FLAC file with a known set of initial metadata
+ blocks, then keep a mirror locally of what we expect the metadata to be
+ after each operation. Then testing becomes a simple matter of running
+ a FLAC__FileDecoder over the dummy file after each operation, comparing
+ the decoded metadata to what's in our local copy. If there are any
+ differences in the metadata, or the actual audio data is corrupted, we
+ will catch it while decoding.

- * Use _next() and _prev() to move around the blocks. This is does not

- * _prev() is slower since it needs to search forward from the front
- * of the file.
- * Use _get_block_type() or _get_block() to access the actual data. The
- * returned object is yours to modify and free.
- * Use _set_block() to write a modified block back. You must have write
- * permission to the original file. Make sure to read the whole
- * comment to _set_block() below.
- * Use _insert_block_after() to add new blocks. Use the object creation
- * functions from the end of this header file to generate new objects.
- * Use _delete_block() to remove the block currently referred to by the
- * iterator, or replace it with padding.
- * Destroy the iterator with FLAC__metadata_simple_iterator_delete()
- * when finished.
- *
- * NOTE: The FLAC file remains open the whole time between _init() and
- * _delete(), so make sure you are not altering the file during
- * this time.
- *
- * NOTE: Do not modify the is_last, length, or type fields of returned
- * FLAC__MetaDataType objects. These are managed automatically.
- *
- * NOTE: If any of the modification functions (_set_block, _delete_block,

- The following are methods for manipulating the defined block types.
- Since many are variable length we have to be careful about the memory
- management. We decree that all pointers to data in the object are
- owned by the object and memory-managed by the object.
-
- Use the _new and _delete functions to create all instances. When
- using the _set_ functions to set pointers to data, set 'copy' to true
- to have the function make it's own copy of the data, or to false to
- give the object ownership of your data. In the latter case your pointer
- must be freeable by free() and will be free()d when the object is
- _delete()d.
-
- The _new and _copy function will return NULL in the case of a memory
- allocation error, otherwise a new object. The _set_ functions return
- false in the case of a memory allocation error.
-
- We don't have the convenience of C++ here, so note that the library
- relies on you to keep the types straight. In other words, if you pass,
- for example, a FLAC__StreamMetaData* that represents a STREAMINFO block
- to FLAC__metadata_object_application_set_data(), you will get an
- assertion failure.
-
