_In_ POBJECT_ATTRIBUTES ObjectAttributes
This function is documented in Windows Driver Kit.
It's very interesting NT System Call... Normally, file deletion is realised as
FileDispositionInformation class in a call to
NtSetInformationFile. When you use
NtDeleteFile, file will be deleted immediately after call (system isn't waiting for close last
HANDLE to file).
You can manipulate ObjectName and RootDirectory members.
If you have only file name as Unicode string, use it as ObjectName.
If you have only a
HANDLE to file, set it as RootDirectory. Set ObjectName as empty string.
DeleteFile (Although it does more than just forwarding the arguments and invoking this procedure.)
