Question : Problem: How does one spawn one thread for each core in C++ on Windows?

I'm writing an image processing algorithm to process a bunch of completely separate images. In an ideal world, I would like to query the operating system for how many cores it has available, and then run a thread on each core.

Is there a way in C++ to query for how many cores are on the machine on which I am running?
Can I spawn a thread for a particular core?

Thanks!

see NumberOfCores.

Here is an example to get OS info. substitute with "Win32_Processor" at appropriate place(s).
