MALLOC_STATS(3) Linux Programmer's Manual MALLOC_STATS(3)
malloc_stats - print memory allocation statistics
#include <malloc.h>
void malloc_stats(void);
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).
For an explanation of the terms used in this section, see
attributes(7).

This function is a GNU extension.
More detailed information about memory allocations in the main arena
can be obtained using mallinfo(3).
