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

Appendix C - Special Functions

Native Functions Callable at Hardware Interrupt Time

Table C-2 lists the functions that are native (providing no mixed-mode glue) and are callable at hardware interrupt time, and also specifies whether you need to call the OTEnterInterrupt function before calling the given function. As in Table C-1, information is added to specify whether the operation is atomic.

Note

Some functions listed in Table C-2 are not documented in this manual because they are specific to Open Transport protocol and device drivers. They are listed here to provide a complete reference.
