This function frees the memory allocated by `fpGetMainFileInfo()`, `fpGetSubFileInfo()`, `fpGetSubFileMetadata()`, and `fpExtractSubFile()`.

## Syntax

    int (pascal *fpFreeStruct) (
        void      *pFile,
        void      *obj);

## Arguments

`pFile` | The identifier of the file. This is a file handle returned from fpOpenFile().
`obj` | A pointer to the result object returned by `fpGetMainFileInfo()`, `fpGetSubFileInfo()`, `fpGetSubFileMetaData`, or `fpExtractSubFile()`.

## Returns

- If the allocated memory is freed, the return value is `KVERR_Success`.
- Otherwise, the return value is an error code.

## Example

The example below frees the memory allocated by `fpGetSubFileInfo()`:

    if ( subFileInfo )
        {
            extractInterface->fpFreeStruct(pFile,subFileInfo);
            subFileInfo = NULL;
        }
