[lib/memory] Add mallinfo support
2006-02-15 Paul Jakma <paul.jakma@sun.com>
* configure.ac: Check for mallinfo, being careful to link test
so we can detect things like umem being used (which doesn't
provide a mallinfo).
* lib/memory.c: (mtype_memstr) new helper function to
return human friendly string for a byte count.
(mtype_stats_alloc) new function, for users to retrieve
number of objects allocated.
(show_memory_mallinfo) New function, show mallinfo statistics
if available.
(show_memory_all_cmd) Call show_memory_mallinfo, if mallinfo
is available.
* lib/memory.h: Export mtype_memstr and mtype_stats_alloc.
Provide a define for a reasonable buffer size for
mtype_memstr.
