RE: [Dev-C++] GetDiskFreeSpaceEx Question

[Hammamur R. <HRa...@ho...>]

Hi, thank you for your help!

I have now used the QuadPart, I written a test program to see what
values I get with using the variables with the QuadPart and without.
All of my partition output the same size, but one outputs different,
i.e. the uliFree is returning different values to uliFree.QuadPart.  I
think I know what the problem is.  The partition outputting different
values has got more then 4 gigs free, all the other partitions have got
less then 2 gigs free.

Could you please tell me how I can fix this, I tried to follow the
Microsoft site, but got more confused.

Thank You!

You might use the uliFreeCaller.QuadPart value, which is a 64-bit
integer.

Or, if you know that the information is < 4GB, you have a 32-bit value
in
uliFreeCaller.LowPart.

Note that since a HD normally is larger than 4 GB, you may not assume
that
you might send the information to a function that only accepts a 'normal
integer value'.

A little improvement would be to Rewrite your function to assume space
in
kB units, and then you call it with:
	MyFunction(unsigned(uliFreeCaller.QuadPart / 1024));

That would be safe up to 4TB disks.
