KeyView 23.2

# fpFilterFile()

This function filters text from an input file to an output file.

DEPRECATED: The `fpFilterFile()` function is deprecated in KeyView 23.2.0 and later. OpenText recommends that you create a `KVDocument` to represent each document, and use fpFilter() or fpFilterToFile() instead.

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

## Syntax

    KVErrorCode pascal fpFilterFile(
        KVFilterSession   session,
        char             *szInputFile,
        char             *szOutputFile,
        KVSummaryInfoEx  *pSummaryInfo );

## Arguments

`session` | A KeyView Filter session that you initialized by calling fpInit().
`szInputFile` | A pointer to the input file.
`szOutputFile` | A pointer to the output file.
`pSummaryInfo` | This argument is reserved. It must be `NULL`.

## Returns

The return value is an error code. See KVErrorCode.

## Discussion

- This function runs in process or out of process. See The Filter Process Model.

- On Windows, `szInputFile` must be in the local Windows code page.

## Example

    error = (int)(*pFilterInterface->fpFilterFile)( pFilter, srcFile, outFile, NULL );
