- File: DNR.c

- Contains: DNR library for MPW
-
- Copyright: © 1989-1995 by Apple Computer, Inc., all rights reserved
-
- Version: Technology: Networking
- Package: Use with MacTCP 2.0.6 and the Universal
- Interfaces 2.1
-
- Change History (most recent first):
- <4> 2/21/96 rrk Typecast each instance of gDNRCodePtr so that
- the selector is passed as a 32-bit value
- <3> 1/23/95 rrk implemented use of universal procptrs
- Changed selector name HINFO to HXINFO
- due to conflict of name in MacTCP header
- Removed use of TrapAvailable and exchanged
- for the TrapExists call.
- Changed symbol codeHandle to gDNRCodeHndl
- Changed symbol dnr to gDNRCodePtr
- Further modifications by Steve Falkenburg, Apple MacDTS 8/91
- Modifications by Jim Matthews, Dartmouth College, 5/91
