RE: [GD-Windows] How to determine total physical memory available ?

[Yannick L. <yle...@ub...>]

Actually it would be a little more complicated since memory can be a =
sum of
different power of 2 (for example if you have one memory chip of 128 MB =
and
another of 64 MB totaling 192MB which is not power of 2).

I'd rather not make this kind of assumption myself and let the system =
give
me the exact numbers ;-)

I guess System Information tool just rounds this number to the next
"reasonable" number.
It knows that memory chips don't come in 1022Mb setups..
So it`s quite easy to round number you get to closest power of 2..

?

I need to determine how much memory is installed on the user's system
somehow.

I used GlobalMemoryStatus but the values returned in the member =
dwTotalPhys
is always underestimating a bit.  For example on my dev machine it =
returns
1022 MB although I have 1024 MB installed.  Same thing happens on all
systems I've tested.

Same thing is reported in dxdiag.exe so they seem to use that function =
as
well.

However, when I use the System Information tool in the system tools of
Windows, it correctly reports 1024 MB.

So anyone knows how I can get the exact information ?
