class OpenSessionWithOptions
Defined at line 316 of file fidling/gen/sdk/fidl/fuchsia.storage.block/fuchsia.storage.block/cpp/fidl/fuchsia.storage.block/cpp/markers.h
Opens a new FIFO-based session on the block device, with additional options.
# Mappings
The `mappings` argument is a list of logical -> physical block mappings, which the server
will transparently apply to device offsets in block FIFO requests within this session.
The mappings are logically contiguous starting from logical offset 0.
This interface is intended to be used internally between nested Block implementations, in
order to provide passthrough I/O. For example, a fixed partition map (e.g. GPT) will serve
a Block protocol for each partition, and will respond to OpenSession requests by calling
OpenSessionWithOptions on the underlying block device, providing mappings which translate
block offsets which are relative to (and bounded by) the partition to absolute offsets on
the device.
Mappings can only ever restrict the visible range of a device; servers will reject mappings
which exceed the range of the device.
If `mappings` is empty, the session channel will be closed with epitaph
`ZX_ERR_INVALID_ARGS`.
