NAME

6       malloc_stats - print memory allocation statistics
7

SYNOPSIS

9       #include <malloc.h>
10
11       void malloc_stats(void);
12

DESCRIPTION

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