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 network connection.
• IotNetworkInterface_t::setReceiveCallback
  Set receive callback.
• IotNetworkInterface_t::setCloseCallback
  Set close callback.
• IotNetworkInterface_t::send
  Send data.
• IotNetworkInterface_t::receive
  Block and wait for receive data.
• IotNetworkInterface_t::close
  Close network connection.
• IotNetworkInterface_t::destroy
  Destroy network connection.
• IotNetworkReceiveCallback_t
  Provide an asynchronous notification of incoming network data.
• IotNetworkReceiveCallback_t
  Provide an asynchronous notification of incoming network data.
