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).
