class ReadAt

Defined at line 2104 of file fidling/gen/sdk/fidl/fuchsia.io/fuchsia.io/cpp/fidl/fuchsia.io/cpp/markers.h

Reads up to 'count' bytes at the provided offset.

Does not affect the seek offset.

## Invariants

* The returned `data.length` will never be greater than `count`.

* If `data.length` is less than `count`, it means that `ReadAt` has hit

the end of file as part of this operation.

* If `data.length` is zero while `count` is not, it means that `offset`

is at or past the end of file, and no data can be read.

* If `count` is zero, the server should perform all the checks ensuring

read access without actually reading anything, and return an empty

`data` vector.

This method requires the [`Rights.READ_BYTES`] right.

Returns `ZX_ERR_OUT_OF_RANGE` if `count` is greater than `MAX_TRANSFER_SIZE`.
