Overview

Package vmnet provides Go bindings for the vmnet framework.

Connect with network interfaces to read and write packets on guest operating systems.

The vmnet framework is an API for virtual machines to read and write packets.

Essentials

  • com.apple.vm.networking: A Boolean that indicates whether the app manages virtual network interfaces without escalating privileges to the root user.

Starting and Stopping Interfaces

  • vmnet_start_interface(_:_:_:): Starts host or shared mode on an interface with a specified configuration.
  • vmnet_interface_set_event_callback(_:_:_:_:): Schedules a callback to be executed when events for the specified interface are received.
  • vmnet_stop_interface(_:_:_:): Stops the interface.

Reading and Writing Packets

  • vmnet_read(_:_:_:): Attempts to read a specified number of packets from an interface.
  • vmnet_write(_:_:_:): Attempts to write specified packets to an interface.

Data Types

  • vmnet_return_t: Values returned by functions in the vmnet Framework.
  • vmpktdesc: Describes a packet.
  • interface_ref: A virtual network interface.
  • interface_event_t: Interface event types.
  • operating_modes_t: The operating modes for an interface.

Constants

  • interface_desc XPC Dictionary Keys: XPC dictionary keys supported by the parameter passed to the function to describe the parameters of the network interface.
  • interface_param XPC Dictionary Keys: XPC dictionary keys used by the argument returned by the completion handler of the function that describes the parameters that should be used to configure the network interface.
  • event XPC Dictionary: XPC dictionary keys used by the value returned to the client in the callback specified by the function that provides information about the callback event.

Variables

  • vmnet_enable_virtio_header_key
  • vmnet_read_max_packets_key
  • vmnet_write_max_packets_key
