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).
