## Detailed Description

This module contains structure definitions for the representation of FLAC format components in memory. These are the basic structures used by the rest of the interfaces.

First, you should be familiar with the FLAC format. Many of the values here follow directly from the specification. As a user of libFLAC, the interesting parts really are the structures that describe the frame header and metadata blocks.

The format structures here are very primitive, designed to store information in an efficient way. Reading information from the structures is easy but creating or modifying them directly is more complex. For the most part, as a user of a library, editing is not necessary; however, for metadata blocks it is, so there are convenience functions provided in the metadata module to simplify the manipulation of metadata blocks.

Note
  It's not the best convention, but symbols ending in _LEN are in bits and _LENGTH are in bytes. _LENGTH symbols are #defines instead of global variables because they are usually used when declaring byte arrays and some compilers require compile-time knowledge of array sizes when declared on the stack.
