Is there a system call that tells me how much memory is installed/available?  I'm looking for the most straight-forward, easy to use function.  I'm trying to avoid having to 'walk the heap", calculating for myself.

thx.

You can use GlobalMemoryStatus/GetFreeSpace functions.

Does this require compiling with MFC or any other special libraries?  I should have mentioned that my application is a vanilla C program.  It does not and ideally will not need to link to anything other than the base C language stuff?

thx.

No, not must MFC or OWL. It is pure Windows API

but it is windows, so I'll need to link in all that stuff -- which I don't want to do.  Is there a system call that is part of the base os?
