# metadata.h File Reference

## Detailed Description

This module provides functions for creating and manipulating FLAC metadata blocks in memory, and three progressively more powerful interfaces for traversing and editing metadata in FLAC files.

See the detailed documentation for each interface in the metadata module.

`#include <sys/types.h>`
`#include "export.h"`
`#include "callback.h"`
`#include "format.h"`
