Inside Macintosh: Networking With Open Transport / Part 2 - Open Transport Reference

Appendix A - Open Transport and XTI

Open Transport Programming Interfaces

The Open Transport library includes three related client programming interfaces: XTI-style, preferred C, and preferred C++. The XTI-style interface includes the C-language XTI functions, plus some Open Transport extensions. XTI is not the preferred interface for the Macintosh because it handles errors through the use of a global variable. Nevertheless, an XTI interface is provided to ease porting of existing XTI client applications.

IMPORTANT

The preferred-C interface of Open Transport is based on XTI but is not identical with it. As a result, some elements have no XTI counterparts, and those that have counterparts are not necessarily identical with them. For definitive information about XTI, refer to the X/Open Transport Interface specification.
