NetpOpenConfigData NetpOpenConfigDataEx
Author:
John Rogers (JohnRo) 02-Dec-1991
Environment:
Portable to any flat, 32-bit environment. (Uses Win32 typedefs.) Requires ANSI C extensions: slash-slash comments, long external names.
Revision History:
02-Dec-1991 JohnRo Created this routine, to prepare for revised config handlers. (Actually, I swiped some of this code from RitaW.) 06-Jan-1992 JohnRo Added support for FAKE_PER_PROCESS_RW_CONFIG handling. 09-Jan-1992 JohnRo Try workaround for lib/linker problem with NetpIsRemote(). 22-Mar-1992 JohnRo Added support for using the real Win32 registry. Added debug code to print the fake array. Fixed a UNICODE bug which PC-LINT caught. Fixed double _close of RTL config file. Fixed memory _access error in setting fake end of array. Use DBGSTATIC where applicable. 05-May-1992 JohnRo Reflect movement of keys to under System\CurrentControlSet\Services. 08-May-1992 JohnRo Use <prefix.h> equates. 21-May-1992 JohnRo RAID 9826: Match revised winreg error codes. 08-Jul-1992 JohnRo RAID 10503: srv mgr: repl dialog doesn't come up. Added more debug output to track down bad error code during logoff. 23-Jul-1992 JohnRo RAID 2274: repl svc should impersonate caller. 22-Sep-1992 JohnRo Avoid GP fault printing first part of winreg handle. 28-Oct-1992 JohnRo RAID 10136: NetConfig APIs don't work to remote NT server. 12-Apr-1993 JohnRo RAID 5483: server manager: wrong path given in repl dialog.

Routine Description:
This function opens the system configuration file.
Arguments:
ConfigHandle - Points to a pointer which will be set to point to a net config handle for this section name. ConfigHandle will be set to NULL if any error occurs.
SectionName - Points to the new (NT) section name to be opened.
ReadOnly - Indicates whether all access through this net config handle is to be read only.
Return Value:
NET_API_STATUS - NO_ERROR or reason for failure.
