NAME

6       malloc_stats - print memory allocation statistics
7

LIBRARY

9       Standard C library (libc, -lc)
10

SYNOPSIS

12       #include <malloc.h>
13
14       void malloc_stats(void);
15

DESCRIPTION

17       The malloc_stats() function prints (on standard error) statistics about
18       memory allocated by malloc(3) and related functions.   For  each  arena
19       (allocation  area), this function prints the total amount of memory al‐
20       located and the total number of bytes consumed by  in-use  allocations.
21       (These two values correspond to the arena and uordblks fields retrieved
22       by mallinfo(3).)  In addition, the function prints the sum of these two
23       statistics  for  all arenas, and the maximum number of blocks and bytes
24       that were ever simultaneously allocated using mmap(2).
