# KVSubFileMetaData

DEPRECATED: The `KVSubFileMetaData` structure is deprecated in KeyView 23.2.0 and later. OpenText recommends that you access metadata using the metadata API described in Use the Metadata API.

This structure is still available for existing implementations, but it might be incompatible with new functionality and might be removed in future.

This structure contains a count of the number of metadata elements extracted from a mail file, and a pointer to the first element of the array of elements. It is initialized by calling fpGetSubFileMetaData(). This structure is defined in `kvxtract.h`.

    typedef struct  tag_KVSubFileMetaData
    {
        KVStructHeader;
        int                nElem;
        KVMetadataElem**   ppElem;
        unsigned long      infoFlag;
    }
    KVSubFileMetaDataRec, *KVSubFileMetaData;

## Member Descriptions

`KVStructHeader` | The version of the structure. See KVStructHead.
`nElem` | The number of metadata fields contained in the array.
`ppElem` | A pointer to an array of pointers that are the memory addresses of metadata field values in the KVMetadataElem structure.
`infoFlag` | A bitwise flag that defines additional properties of the extracted metadata. The following flag is available: `KVSubFileMetaInfoFlag_CharsetConverted`—Indicates that the metadata’s character set was converted.
