SessDel.c
Abstract:
This file contains RxNetSessionDel().
Author:
John Rogers (JohnRo) 18-Oct-1991
Environment:
Portable to any flat, 32-bit environment. (Uses Win32 typedefs.) Requires ANSI C extensions: slash-slash comments, long external names.
Revision History:
18-Oct-1991 JohnRo Created. 21-Oct-1991 JohnRo Fixed bug: RxNetSessionEnum wants BufPtr as "LPBYTE *". Added debug output. 27-Jan-1993 JohnRo RAID 8926: NetConnectionEnum to downlevel: memory leak on error. Use PREFIX_ equates.
