Eric Andersen53601822002-12-05 21:12:42 +000065 There are 3 ways BusyBox can handle buffer allocations:
66 - Use malloc. This costs code size for the call to xmalloc.
67 - Put them on stack. For some very small machines with limited stack
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +000068 space, this can be deadly. For most folks, this works just fine.
Eric Andersen53601822002-12-05 21:12:42 +000069 - Put them in BSS. This works beautifully for computers with a real
70 MMU (and OS support), but wastes runtime RAM for uCLinux. This
71 behavior was the only one available for BusyBox versions 0.48 and
72 earlier.
