      @param eventMask A bit mask indicating the keychain events that your application wishes to be notified of. See SecKeychainEventMask for a description of this bit mask. The Keychain Manager tests this mask to determine the keychain events that you wish to receive, and passes these events in the keychainEvent parameter of your callback function. See SecKeychainEvent for a description of these events.
      @param userContext A pointer to application-defined storage that will be passed to your callback function. Your application can use this to associate any particular call of SecKeychainAddCallback with any particular call of your keychain event callback function.
    @result A result code.  See "Security Error Codes" (SecBase.h).
