File Content Extraction 25.2
Filter SDK C Programming Guide

# 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 `KVMetadataList*`. On success, `fpGetMetadataList()` will set this to the address of a new KVMetadataList struct that contains the function pointers for accessing the metadata elements.

## Returns

- If the call is successful, the return value is `KVError_Success`.
- If the call is not successful, the return value is an error code that indicates the problem.

## Lifetimes and Memory Management

- If the function returns `KVError_Success`, you must free the `KVMetadataList` pointer using its `fpFree()` function.

- You must free `ppMetadataList` before you close `pDocument`.

## Example

    const KVMetadataList* metadataList = NULL;
    error = filterInterface->fpGetMetadataList(pDocument, &metadataList);
