This is a bit inconsistent with other address types (hwaddr, ram_addr_t), no? -> git grep "_size_t" What sticks out are "external" mach_vm_size_t and png_size_t. To me, it logically makes sense that both types are equal, because we're operating on the same address space (with the same size). So at least I don't see the benefit here, but I'd love to be enlightened :) -- Thanks, David / dhildenb
