NAME

       malloc_stats - print memory allocation statistics

LIBRARY

       Standard C library (libc, -lc)

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).
