Change owner and group of a file or directory.

There are a collection of Unix functions for changing file ownership as shown above. There is not a direct mapping of these functions to Windows functions because of the different security and permissions models used between the two systems. Traditional Unix code (and most code still) use a simpler model than the more advanced ACL (Access Control List). This will necessitate a significant change in the source code. You may either update the change in-place or create a helper function to perform the same intent. Because of the greater complexity of ACLs the Windows source code is more complex and lengthy. Therefore it is usually better to create helper functions, particularly when the functionality will be used more than one time.
