Fill info with the pointer and sizes of the memory in mem that can be accessed according to flags.

This function can return FALSE for various reasons: - the memory backed by mem is not accessible with the given flags. - the memory was already mapped with a different mapping.

info and its contents remain valid for as long as mem is valid and until Memory.unmap is called.

For each call, a corresponding Memory.unmap call should be done.
