Change History (most recent first):
$Log: MoreSCF.c,v $
Revision 1.10 2003/04/14 15:50:55
Use CFQAllocate/Deallocate to prevent "malloc(0) returns NULL" problems.
Revision 1.9 2003/02/26 20:50:42
<rdar://problem/3183087> Added support for V.92 modem hold.
Revision 1.8 2003/02/26 12:34:35
Fixed up the code that sets the default config method for IPv4 entities.
Revision 1.7 2002/11/14 20:22:33
Quieten a debug message when creating new sets.
Revision 1.6 2002/11/09 00:01:46
Include our prototype early to flush out any missing dependencies. Convert nil to NULL. Convert MoreAssertQ to assert.
Revision 1.5 2002/08/14 20:09:05
Updated unique ID code based on engineering feedback.
Revision 1.4 2002/08/14 16:35:33
Certain hardwired defaults now get different values on 10.2 and later. Others get different values on 10.1.3 and later. Changed how I create new PPP entities to accomodate 10.2 PPP vs PPPoE changes.
Revision 1.3 2002/08/14 13:43:31
Work around Jaguar incompatibility caused by Radar ID 3024328.
Revision 1.2 2002/01/22 06:22:21
Changes to accomodate new port scanner API. Specifically, made significant changes to MoreSCNewService. Also some minor changes for C++ compatibility.
Revision 1.1 2002/01/16 22:52:19
First checked in.

#if WORKAROUND_RADAR_ID_3024328
// This implementation of SCPreferencesPathCreateUniqueChild was
// largely stolen from the implementation on Mac OS X 10.1. By
// using it we work around a problem [3024328] with Apple menu
// location switching that's triggered by the new implementation
// of SCPreferencesPathCreateUniqueChild on Mac OS X 10.2.
//
// The difference between this version and the original 10.1 version
// is that this code finds the ID that's one larger than the largest ID.
// The 10.1 code finds the first unused ID, which can results
// in possible ID reuse.
//
// The 10.2 version does the same thing using GUIDs, but that
// generates very long ID strings, which triggers the bug mentioned
// above.
//
// When that problem is fixed I'll include conditional code
// to call the real SCPreferencesPathCreateUniqueChild or this
// compatibility code depending on the running system version.
