Eric Andersenc9f20d92002-12-05 08:41:41 +000064 help
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.

586### This option is most likely only beneficial for newer compilers

597 library lacks large file support for large files. Some of the
Denis Vlasenkof545be02007-10-07 17:06:26 +0000598 programs that can benefit from large file support include dd, gzip,

690 dmalloc support:
691 ----------------
Eric Andersenc9f20d92002-12-05 08:41:41 +0000692 This enables compiling with dmalloc ( http://dmalloc.com/ )
693 which is an excellent public domain mem leak and malloc problem
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000694 detector. To enable dmalloc, before running busybox you will
Eric Andersenc9f20d92002-12-05 08:41:41 +0000695 want to properly set your environment, for example:
696 export DMALLOC_OPTIONS=debug=0x34f47d83,inter=100,log=logfile
697 The 'debug=' value is generated using the following command
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000698 dmalloc -p log-stats -p log-non-free -p log-bad-space \
699 -p log-elapsed-time -p check-fence -p check-heap \
700 -p check-lists -p check-blank -p check-funcs -p realloc-copy \

Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000705 This enables compiling with Electric-fence support. Electric
Eric Andersen88c916b2003-10-22 09:58:56 +0000706 fence is another very useful malloc debugging library which uses
Eric Andersenc7bda1c2004-03-15 08:29:22 +0000707 your computer's virtual memory hardware to detect illegal memory
