+The structure fields contain the following information:

+              mmap(2) (i.e., memory allocated on the heap).  This figure
+              includes both in-use blocks and blocks on the free list.
+
+       ordblks
+              The number of ordinary (i.e., non-fastbin) free blocks.
+
+       smblks The number of fastbin free blocks (see mallopt(3)).
+
+       hblks  The number of blocks currently allocated using mmap(2).
+              (See the discussion of M_MMAP_THRESHOLD in mallopt(3).)
+
+       hblkhd The number of bytes in blocks currently allocated using
+              mmap(2).
+
+       usmblks
+              This field is unused, and is always 0.  Historically, it
+              was the "highwater mark" for allocated space—that is, the
+              maximum amount of space that was ever allocated (in
+              bytes); this field was maintained only in nonthreading
+              environments.
+
+       fsmblks
+              The total number of bytes in fastbin free blocks.
+
+       uordblks
+              The total number of bytes used by in-use allocations.
+
+       fordblks
+              The total number of bytes in free blocks.
+
+       keepcost
+              The total amount of releasable free space at the top of
+              the heap.  This is the maximum number of bytes that could
+              ideally (i.e., ignoring page alignment restrictions, and
+              so on) be released by malloc_trim(3).
