Thanks for your reply.

But while trying to do this, is there a guarantee that

1. the mapping will succeed (I am guessing not.)?

2. even if it succeeds, the mapped address range will
*not* be already in use by the process?

I am guessing some form of pre-reserving the VM
address space range may be necessary - perhaps done
during compilation or linking the programs concerned.
