Is is possible to add to Phobos standard functions (intrinsics, if necessary) that give some information about the C stack? Things like: - Available space left on the stack (for a thread) - Total size of the stack at program start - The direction of stack growth (see for example http://www.devx.com/tips/Tip/37412 ). - Starting address of the stack Probably on some systems/situations such information is not available, for example the stack can be implemented on a heap, so the function that tells the direction of stack growth can return an enum with three values: UP, DOWN, UNKNOWN. Similar information can be used for low-level programming. I am not expert about this, so maybe this can't be done. For example I've added a small enhancement request for performance that can get better if it knows the available free stack space left (but this is not an usage case, because it's meant to be a feature implemented by the compiler): http://d.puremagic.com/issues/show_bug.cgi?id=4357 Bye, bearophile
