The Windows API function CreateFile function allows you to specific the desired access. There are three options read, write and delete. If you get a handle from CreateFile requesting Delete access how do you then delete the file using the returned handle? The DeleteFile function takes the file name, not the handle.
Big Picture: When saving files from my application I write out to a temporary file first, then delete the "real" file and rename the temporary file to the real name. I have started to see problems with search indexers, or anti virus/spyware opening the file for reading but not allowing deletes. This causes my save to fail when moving the files around. I have changed my open code to request delete access to make sure I can delete the file when it comes time to save.
This all works fine but I still have a gap where a third party application could grab my file. Since I have an open handle to both the temporary and real files I was looking for a way to perform the delete and rename functions using those handles. The only option I can find is to close the handles and then call the DeleteFile and MoveFile functions. Actually I am currently using the ReplaceFile API function to perform those steps, but it too has file names passed in and will not work unless I close my handles first.
I still need to support XP and cannot start using the new transaction file functions. Is there any way to keep the files locked and still delete/rename them?
