+.SH DESCRIPTION
+The
+.BR malloc_stats ()
+function prints (on standard error) statistics about memory allocated by
+.BR malloc (3)
+and related functions.
+For each arena (allocation area), this function prints
+the total amount of memory allocated
+and the total number of bytes consumed by in-use allocations.
+(These two values correspond to the
+.I arena
+and
+.I uordblks
+fields retrieved by
+.BR mallinfo (3).)
+In addition,
+the function prints the sum of these two statistics for all arenas,
+and the maximum number of blocks and bytes that were ever simultaneously
+allocated using
+.BR mmap (2).
