Q3Controller_GetListChanged

You can use the Q3Controller_GetListChanged function to determine whether the list of available controllers has changed.

TQ3Status Q3Controller_GetListChanged (
TQ3Boolean *listChanged, 
unsigned long *serialNumber);

listChanged

On exit, a Boolean value that indicates whether the list of available controllers has changed (kQ3True) or not (kQ3False).

serialNumber

On entry, a serial number of the list of available controllers. On exit, the current serial number of that list.

DESCRIPTION

The Q3Controller_GetListChanged function returns, in the listChanged parameter, a Boolean value that indicates whether the list of available controllers has changed since the time the serial number passed in the serialNumber parameter was generated. If the list has changed, the new serial number is returned in the serialNumber parameter; otherwise, the serialNumber parameter is unchanged.
