Do you have any clue about the error that I am getting on testing the demo code?:

it says that there is error at error = tobii_wait_for_callbacks( NULL, 1, &device );
Saying that we cannot change from ‘int’ to ‘tobii_device_t* const*’

Is it okay if I remove that “NULL” and just put tobii_wait_for_callbacks( 1, &device); ??
