DARWIN for Extended API Constants and Types
Chapter 25 DARWIN for Extended API Constants and Types
25.1 Overview of the DARWIN Constants
This Extended API provides the following types of constants.
In Visual C/Visual C++, the constants from chapter 11.1 are inherited. Also,
constants, retrieval code types, range types, and skip range constants have been
added for the Extended API. See section 25.2.
The constants for Visual Basic and Visual Basic.NET/C# are listed in section 25.2.
