# KVStructHead

This structure contains the current KeyView version number, and is the first member of other structures. It enables OpenText to modify the structures in future releases, but to maintain backward compatibility. Before you initialize a structure that contains the `KVStructHead` structure, use the macro `KVStructInit` to initialize `KVStructHead`. The structure and macro are defined in `kvstructhead.h`.

    typedef struct _KVStructHead
    {
       WORD        version;
       WORD        size;
       DWORD       reserved;
       void        *internal;
    }
    KVStructHeadRec, *KVStructHead;

## Member Descriptions

`version` | The current KeyView version number. This is a symbolic constant (KeyviewVersion) defined in `kvstructhead.h`. This constant is updated for each KeyView release.
`size` | The size of the `KVStructHeadRec`.
`reserved` | Reserved for internal use.
`internal` | Reserved for internal use.

## Example

    KVPanopticonEncryptionInfo encryptionInfo;
    KVStructInit(&encryptionInfo);
