Guaranteed to be aligned for _any_ type, isn't it ?
Any type that is not bigger than the memory size allocated. I'm pretty sure that the ANSI requirement for malloc and new does not require alignment to 8/16 byte blocks for memory allocations of a single byte (for example). This means that, to be pedantic, a 1 byte allocation is not guaranteed to be aligned for a double (for example). However, since this is a silly example, for all practical purposes you are correct. Also, some implementation may well guarantee alignment for small allocations. Nevertheless, my rather terse comment about being guaranteed to return memory aligned for an object of that size was probably a bit too terse, so thanks for the quotes and clarification. Dave
