Eric Andersen | 5360182 | 2002-12-05 21:12:42 +0000 | [diff] [blame] | 45 | There are 3 ways BusyBox can handle buffer allocations: |
| 46 | - Use malloc. This costs code size for the call to xmalloc. |
| 47 | - Put them on stack. For some very small machines with limited stack |
| 48 | space, this can be deadly. For most folks, this works just fine. |
| 49 | - Put them in BSS. This works beautifully for computers with a real |
| 50 | MMU (and OS support), but wastes runtime RAM for uCLinux. This |
| 51 | behavior was the only one available for BusyBox versions 0.48 and |
| 52 | earlier. |
