Icon Services Gestalt Selector

Before calling any Icon Services functions, your application should pass the selector gestaltIconUtilitiesAttr to the Gestalt function.



 
enum {

    gestaltIconUtilitiesAttr= 'icon'

};

gestaltIconUtilitiesAttr: The Gestalt selector passed to determine which features of Icon Services are present. The Gestalt function produces a 32-bit value whose bits you should test to determine which Icon Services features are available.

You can use the following bit mask to test for the presence of Icon Services.



 
enum{

    gestaltIconUtilitiesHasIconServices = 4

};

gestaltIconUtilitiesHasIconServices: If this bit is set, Icon Services is installed.
