Parallels C API Reference Guide
Creates a new handle of type PHT_APPLIANCE_CONFIG.
The handle is necessary to create and configure an appliance download configuration. If you would like to create a new appliance download configuration, use this function to create the handle first and then use the handle functions to configure the appliance info.
It is the responsibility of the caller to free the handle with the PrlHandle_Free call when it is no longer needed.
