# mongoc_stream_flush()

## Synopsis

    int
    mongoc_stream_flush (mongoc_stream_t *stream);

## Parameters

- `stream`: A mongoc_stream_t.

This function shall flush any buffered bytes in the underlying stream to the physical transport. It mimics the API and semantics of `fflush()`, forcing a write of user space buffered data.

Not all stream implementations may implement this feature.

## Returns

0 is returned on success, otherwise `-1` and `errno` is set.

Created using Sphinx 1.5.3, based on Sphinx Readable Theme.
