Gestalt Selector and Response Values

You can pass the gestaltQTVRMgrVers selector to the Gestalt function to get the version of the QuickTime VR Manager. You can pass the gestaltQTVRMgrAttr selector to the Gestalt function to get information about the QuickTime VR Manager. Gestalt returns information to you by setting or clearing bits in the  response parameter. The selectors and bits currently used are defined by constants:

enum {
    gestaltQTVRMgrAttr                  = FOUR_CHAR_CODE('qtvr'),
    gestaltQTVRMgrVers                  = FOUR_CHAR_CODE('qtvv'),
    gestaltQTVRMgrPresent                           = 0,
    gestaltQTVRObjMoviesPresent                     = 1,
    gestaltQTVRCylinderPanosPresent                 = 2
};
