Is there a documentation explaining somewhere very clearly how a 32 bits process is running in a 64 bits capable OS? Because I'm wondering what kind of address is ok for copyin when the address-space in the kernel is 64 bits. I have some problem understanding how providing my user space address from a 32 bits process is going to work in every case when the address space can be 64 bits. Unless 32 bits processes can't be executed in the last 32 bits of the 64 bits address space. This email sent to site_archiver@lists.apple.com
