The IoIsFileOriginRemote routine determines whether a given file object is for a remote create request.
FileObject [in]Pointer to a file object for the file.
IoIsFileOriginRemote returns TRUE if the file object was created to satisfy a remote create request, otherwise FALSE.
File system filter drivers call IoIsFileOriginRemote for a file object to determine whether it represents a remote create request.
IoIsFileOriginRemote must be called after the create request has entirely completed. In other words, it cannot be called in the create dispatch ("pre-create") path or the create completion ("post-create") path.
IoIsFileOriginRemote checks the FO_REMOTE_ORIGIN flag on the file object pointed to by FileObject. Network file systems set or clear this flag by calling IoSetFileOrigin.
