Hi, I''m writing a class to wrap the WinAPI file functions. (I''ve never actually used them, but they don''t look very nice so I''d like to get them out of the way). Anyway the question is: should I use LockFile to lock files for the whole time they are in use, or not? The API documentation isn''t very clear on the subject. Thanks

It really depends on whether you want the user to be able to access the file while your program is running.

If you were writing a word processor for example, maybe the user might want to use the files you opened in another application or process. In this case, I wouldn''t lock the files.

On the other hand, if your program required a pristine condition from the file (such as loading a save game), and a corrupt file could cause problems (crashes, invalid data, etc), you might want to lock the file.
