Returns <tt>nil</tt> if the underlying operating system does not support <em>fsync(2)</em>. Note that <tt>fsync</tt> differs from using <tt>IO#sync=</tt>. The latter ensures that data is flushed from Ruby's buffers, but doesn't not guarantee that the underlying operating system actually writes it to disk. full_name: IO#fsync is_singleton: false name: fsync params: | ios.fsync => 0 or nil visibility: public
