/// <summary>
/// Use GetOriginatorProcessId to get the process ID (PID) of the process that originated the operation.
/// Call this method only from the callback / event handlers.
/// Do not call this method from handlers for OnReadFile, OnWriteFile and other callbacks that work with opened
/// files, as that callbacks can be initiated by the system components (cache manager, memory manager etc.).
/// Instead do the following:
/// Call GetOriginatorProcessId from OnCreateFile or OnOpenFile event handlers / callbacks;
/// Store obtained information somewhere and store the reference to this information in the UserContext;
/// When you need to check the originator information in some file-related callback, access the stored information via UserContext
/// </summary>
/// <remarks>
/// Note that the PID is guaranteed to be unique only during lifetime of the process. When the process is
/// terminated, it's PID can (in theory) be used by other process. In fact this never happens, but such
/// possibility is documented by Microsoft.
