malloc() does not pre-zero memory, but it hands you memory which has been pre-zeroed by the kernel unless you've used it before. Your test program makes only one malloc() call, so you get memory that has never been used before. > ...it seems like it's saying that malloc (as opposed to calloc) is NOT > pre-zeroed. Is there a different document I should be reading? No, but nowhere in the standard does it say that memory allocated with malloc() must contain non-zero garbage. If that is what you want, though, read the TUNING section in the malloc(3) man page.
