mongoc_stream_flush()#

Synopsis#

int
mongoc_stream_flush (mongoc_stream_t *stream);

Parameters#

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.
