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

Appendix C - Special Functions

Functions That Allocate Memory

Table C-4 lists all Open Transport functions that allocate memory on your behalf and therefore require that you call either the InitOpenTransport function or the InitOpenTransportUtilities function before calling them.

Note

Some functions listed in Table C-4 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.
