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

Chapter 24 - Mappers Reference

Functions

This section describes functions that you use only with mappers to manage the mapping of names to protocol addresses for a network. These functions fall into three categories: functions you use to create a mapper, functions you use to register a name or delete a registered name, and functions you use to search for a name or to validate a name-address pair.

As with other provider functions, you can execute mapper functions synchronously or asynchronously. However, Open Transport provides no function to cancel outstanding asynchronous mapper functions. The only way to cancel such functions is to close the mapper by calling the OTCloseProvider function, described in the chapter "Providers Reference".

You can also use general provider functions with mappers. You use these functions to change a function's modes of operation (for example, to blocking). General provider functions are described in the reference section of the chapter "Providers".
