Networking

Functions of the network abstraction component.

The network abstraction component does not declare functions, but uses function pointers instead. This allows multiple network stacks to be used at the same time. Libraries that require the network will request an IotNetworkInterface_t parameter. The members of the IotNetworkInterface_t will be called whenever the library interacts with the network.

The following function pointers are associated with an IotNetworkInterface_t. Together, they represent a network stack.

• IotNetworkInterface_t::create
  Create a new network connection.
• IotNetworkInterface_t::setReceiveCallback
  Register an IotNetworkReceiveCallback_t.
• IotNetworkInterface_t::send
  Send data over a return connection.
• IotNetworkInterface_t::receive
  Block and wait for incoming network data.
• IotNetworkInterface_t::close
  Close a network connection.
• IotNetworkInterface_t::destroy
  Free resources used by a network connection.
• IotNetworkReceiveCallback_t
  Provide an asynchronous notification of incoming network data.
