# fpCloseStream()

This function closes a document stream opened by using `fpOpenStream()`.

DEPRECATED: The `fpCloseStream()` function is deprecated in KeyView 23.2.0 and later.

OpenText recommends that instead of calling fpOpenStream() or fpOpenStreamEx2(), you create a `KVDocument` to represent each document, by calling fpOpenDocumentFromStream(). When you no longer need a `KVDocument`, call fpCloseDocument().

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

## Syntax

    BOOL pascal fpCloseStream( 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 call is successful, the return value is `TRUE`.
- If the call is unsuccessful, the return value is `FALSE`.

## Discussion

After filtering is complete, call this function to free the memory allocated by `fpOpenStream()` or `fpOpenStreamEx2()`.
