PROTOCOLS

Connector

Defined in fuchsia.device.fs/connector.fidl

A connector lets a client forward the server end of a protocol.

Connect

Forward a server end of a protocol so that it can be connected.

  • request server the server end of the protocol to be served. The FIDL protocol that this speaks is determined out-of-band.
  • response This function has no response. The function is one-way to match the pipelining behaviors of other virtual filesystems.

OrdinalFieldTypeDescription
connector client_end:Connector

This is the connector to be installed in devfs. Connect() will be called when a client connects to this node in the filesystem. Optional: If this is not provided then an empty node will appear in devfs.
class_name string:255

This is the class name for installing this node in devfs. The node will be placed within /dev/class/{class_name}. If class_name does not exist under /dev/class/ it will be created. Optional: If this is not provided then the node will only be added via topological path.
inspect handle<vmo>

This is a vmo of inspect data that will be installed in devfs. Optional: If this is not provided then the devfs's inspect data will be empty.
connector_supports ConnectionType

The connection types that are supported by the |connector| given. The driver framework should handle connection types that are not supported by the connector. If not provided, only the device type is assumed as supported by the connector.

Added: HEAD
controller_connector client_end:Connector

This is the controller connector to be installed in devfs. Connect() will be called when a client connects to the device_controller connection for this node in the filesystem. Optional: If this is not provided then the Node will handle the connection natively. This option should only be used by the compat shim or in tests
