+======== Sample documentation ========
+fsync() - synchronize changes to a file
+fdatasync() - synchronize the data of a file
+fsync ( resource $stream ) : bool
+Request that all data for the open file pointer $stream is to be transferred to the storage device. The manner of synchronization is OS dependent. The fsync() function shall not return until the system has completed that action or until an error is detected.
+Returns true on success or false on failure.
+If the resource indicated by $stream is not a file pointer, an E_WARNING is emitted.
