File Content Extraction 26.1
Filter SDK C Programming Guide

# fpCanFilterStream()

This function determines whether the format of the file to which a stream points is supported by File Content Extraction.

DEPRECATED: The `fpCanFilterStream()` function is deprecated in KeyView 23.2.0 and later. OpenText recommends that you create a `KVDocument` to represent each document, and use fpCanFilter() 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 fpCanFilterStream( KVFilterSession session, void *pStreamContext );

## Arguments

`session` | A Filter session that you initialized by calling fpInit().
`pStreamContext` | A pointer returned from fpOpenStream() or fpOpenStreamEx2().

## Returns

- If the file format is supported, the return value is `KVERR_Success`.
- If the file format is not supported, the return value is an error code. See KVErrorCode.
