I mis-wrote: Linux's minimum malloc, malloc(1), will occupy 16 bytes of heap as you stated. Malloc(n) on Linux will allocate the next multiple of 8 bytes for (n+4), minimum 16 bytes total. Observed malloc behavior on Linux - Malloc'd bytes on the left, heap occupied by that malloc on right: 1 16 2 16 3 16 4 16 5 16 6 16 7 16 8 16 9 16 10 16 11 16 12 16 13 24 14 24 15 24 16 24 17 24 18 24 19 24 20 24 21 32 22 32 23 32 24 32 25 32 26 32 27 32 28 32 29 40 30 40 31 40 32 40 33 40 34 40 35 40 36 40 37 48 38 48 39 48 40 48 41 48 42 48 43 48 44 48 45 56 46 56 47 56 48 56 49 56 50 56 51 56 52 56 53 64 54 64 55 64 56 64 57 64 58 64 59 64 60 64 61 72 62 72 63 72 64 72 65 72 etc... ____________________________________________________________________________________ Get your own web address.
