I have a file that exists on a server that multiple machines will be accessing using the program that I am writing. They access the file using the _fsopen command with _SH_DENYRW permissions. Each of the computers open the file, and checks the timestamp within the file. If it is not over the specified age, that machine will add data and close the file. If the timestamp is over the specified age, it needs to be deleted.
Can I just close the file and then delete it? But I'm thinking that by closing the file, one of the other machines will gain access to it and then it wont be able to be deleted. Is there a way to close the file, but keep ownership of it so no one else can access it before I delete it?
