Not necessarily. On Unix there is also a difference between closing a 
file and calling fsync() on it. And even then there are sometimes 
additional things you may have to do to survive sudden power loss, such 
as first using fcntl(fd,F_FULLFSYNC) on OS X in case you want to OS to 
also instruct the disk controller to flush its internal caches (if 
supported by the disk).
