malloc_stats
MALLOC_STATS(3) Linux Programmer's Manual MALLOC_STATS(3)
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 alloca-
tions. (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).
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).
