[M3devel] More on threading

[Jay K]

1. That is the expected result. Please please look closer.
2. Yeah, the sample I derived from is a bit buggy but I think I fixed its bugs, I vaguely recall.


I'm sure there's no problem here, anyway. At least on Windows 2000 and newer.
Maybe on NT 3.x, NT 4.0, Win9x, maybe depending on the install of IE. But I doubt anyone cares.


Heck, for a very long time, this code didn't really work for MacOSX, FreeBSD, NetBSD, OpenBSD, Solaris,
only Windows, Linux, OSF/1, and nobody seemed to notice.. (it falls back to the local
IPv4 address, which isn't very unique typically).
I think it works everywhere now, through heavy #ifdef.
(Given the level of #ifdef, I wonder if we should either combine Windows and Posix into
one file, or split up Posix into multiple files, or just leave it alone..)


Thanks,
  - Jay

Jay:
 
For Windows 2000 SP4, using Visual C++ 2005 Express Edition:
 
1.  I tried building the MachineID.c program in the first example link, but it runs into an unresolved symbol at link time.
 

cl MachineID.c

2.  I was able to build the program in the 2nd link.  Here is the output from running this program:

It should work.

Mika, what made you think cm3 doesn't work on Windows 2000??

I don't think anything has been remotely suggested.

Jay, since I have a Windows2000 system, I can test the MAC address discovery (or anything else you need).  Just let me know.

Agreed -- I don't know of any reason Windows 2000 wouldn't work.

Or possibly even older. The main "upgrade driving" factor is what the C toolset/runtime supports.

And I've tested building with quite old C toolsets.

Hm. Maybe the new-ish MAC address discovery code doesn't work on older systems? That could be.

I could make that use GetProcAddress and fallback to the older code.

That is an area with the historical code seemed too non-ideal to stick with, and clearer

more direct code might depend on newer systems.
