A convenience bundle of precondition, data and where for reading into a T as specified by its to_asio_buffers() overload. Data [*MUST] stay around until the operation completes.
[heading Synopsis]
``struct io_req< void >
: public detail::io_req_impl< false >
{
future precondition; // A precondition containing an open file handle for this operation.
std::vector< asio::mutable_buffer > buffers; // A sequence of mutable Boost.ASIO buffers to read into.
off_t where; // The offset from which to read.
};
``
