sync forces "dirty" (modified) filesystem buffers to be written to disk.
public static int sync ()
Returns
On success, zero is returned. On error, -1 is returned and errno is set. Stdlib.GetLastError can be called to obtain the translated error.
Remarks
The filesystem buffer cache is generally write-behind, for best performance. But since the cache is not persistent, it should be flushed periodically. A sync() call is issued by the update daemon periodically.
