	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
result< file_handle::extent_type >	llfio_v2_xxx::maximum_extent (const file_handle &self) noexcept
result< file_handle::extent_type >	llfio_v2_xxx::truncate (file_handle &self, file_handle::extent_type newsize) noexcept
result< std::vector< file_handle::extent_pair > >	llfio_v2_xxx::extents (const file_handle &self) noexcept
	Returns a list of currently valid extents for this open file. WARNING: racy!
result< file_handle::extent_type >	llfio_v2_xxx::zero (file_handle &self, file_handle::extent_type offset, file_handle::extent_type bytes, deadline d=deadline()) noexcept
	Efficiently zero, and possibly deallocate, data on storage. More...
