Is there a list of reserved memory addresses out there - a list of addresses that the memory of a user-space program could never be allocated to? I realize this is most likely per-OS or per-architecture, but I was hoping someone might know some of the more common OSes and Arches. I could only dig one up for a few versions of windows:

for windows NT,2k and XP that would be:

0x00000000 - 0x0000ffff -> lowest page is protected to simplify debugging

0x00001000 - 0x7ffeffff -> memory area for your application

0x7fff0000 - 0x7fffffff -> protected area to keep memory-functions from damaging the following part

0x80000000 - 0xffffffff -> memory where the system including drivers and so on is located

Anyone know about for Linux, or BSD (or anything else, for that matter)?

What's the difference between reserved and committed memory?

as seen on Stack Overflow - Search for 'Stack Overflow'
I understand that memory has to be reserved before being committed. And when it's reserved, no other process can use it. However reserved memory does not count against available RAM. But shouldn't it? Because if no one else can use it, then what good is it being "available"? Or is there some bigger… >>> More
