I am opening a file with read access and allowing subsequent read|write|delete file share access to the file (tailing the file). If the file is deleted during processing is there a way to detect that the file is pending delete (see Files section http://msdn.microsoft.com/en-us/library/aa363858(v=VS.85).aspx)? If some outside process (the owning process) has issued a delete, I want to close my handle as soon as possible to allow the file deletion so as not to interfere with any logic in the owning process.
I'm in C# and see no method of detecting the pending delete. The file was opened using a FileStream object. Is there some method for detecting the delete in C# or in some other windows function?
I would use a different signaling mechanism. (I am making the assumption all file access is within your control and not from a closed external program, mainly due to the flags being employed.)
The only "solution" within those bounds I can think of is a poll on file-access and check the exception (if any) you get back. Perhaps there is something much more tricky (at a lower-level than the win32 file API?!?), but this is already going down the "uhg path" :-)
