NAME

       malloc_stats - print memory allocation statistics

SYNOPSIS

       #include <malloc.h>

       void malloc_stats(void);

DESCRIPTION

       The  malloc_stats()  function prints (on standard error) statistics about memory allocated
       by 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 arena and uordblks fields  retrieved
       by 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 mmap(2).
