Re: How to determine if running on a 32 or 64 bits kernel ?

Perhaps on that particular machine userspace is all 32-bit. It's possible to run 64-bit userspace as well.

It's incredible that it's impossible to determine if os/kernel is 32
or 64 bits (or 128 !) with a small call.

Userspace is easy...it's whatever you compiled for. On the kernel side of things uname generally gives the information, but not always.

From another point of view...if userspace can't tell the bit-size of the kernel, can it possibly matter for userspace?
