# fpGetMetadataList()

Gets the metadata from a document. You can use this function to access all available metadata including document properties, OLE summary information, and XMP metadata. For more information about accessing metadata, see Use the Metadata API.

If the file is a container, you can access metadata for its subfiles by using the Extract API. See the function `fpGetSubFileMetadataList()`.

## Syntax

    KVErrorCode (pascal* fpGetMetadataList)(
        KVDocument pDocument,
        const KVMetadataList** const ppMetadataList);

## Arguments

`pDocument` | A `KVDocument` that you created with fpOpenDocumentFromFile() or fpOpenDocumentFromStream().
`ppMetadataList` | A pointer to a `const KVMetadataList` pointer. On success, this will contain the functions for accessing metadata elements, which must be freed with its `fpFree` function.

## Returns

The return value is an error code.

## Discussion

- You must free the `KVMetadataList` pointer using its `fpFree()` function.
