MALLOC_STATS(3)                                                         Linux Programmer's Manual                                                        MALLOC_STATS(3)

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).
