/*
|
||
|
|
* Example for receiving TCLO commands, polled from the host.
|
||
|
|
* These are used for asynchronous host-to-guest messages,
|
||
|
|
* like resolution changes and clipboard synchronization.
|
||
|
|
*
|
||
|
|
* (These commands are actually part of VMware Tools, not the
|
||
|
|
* SVGA device. They're documented and implemented far better
|
||
|
|
* in the open-vm-tools project. However, we include a very tiny
|
||
|
|
* implemnentation here in order to test features which involve
|
||
|
|
* collaboration between Tools and SVGA, like Unity or Fit-Guest.)
|
||
|
|
*
|
||
|
|
* This sample just writes all incoming and outgoing messages to the
|
||
|
|
* console.
