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

When allocating memory for two different nodes, the resulting memory are the same. Clearly, this will lead to a mistake. This happened in a function. And the process must be in a function.

I currently have a statistics gathering script i run on my Linux servers. One of the stat i gather is total memory in the machine. The script is all perl with the exception of gathering the memory for that i use the following command:

Hi to all,
Recently i am testing an equipment that runs in i586 fedora linux. I have to test mmap function. For that i determined to fill the memory and run the required application to check whether it throws any mmap error regarding low resources.
This is the line that does the allocation. ... (3 Replies)
In a 'C' program,when I am trying to allocate memory with the help of malloc () function, it is allocating the memory up to a certain limit for e.g. in my case, it is 670 MB (approx). malloc() returns NULL if I allocate more than this amount of memory.When I tried
to allocate memory in chunks of... (1 Reply)
I'm new to kernels and C, and I am tinkering around trying to understand OpenBSD's secure memory management. I'm stumped on a couple points.
I've read up on malloc() which was apparently modified years ago to allocate memory using mmap. First question, that would be this here, right?

Hi,
Below is the code snippet I use on Linux (Centos) to retrieve the Process Name, PID and memory consumed on Linux (Centos) host:-
top -b -n 1 | awk -v date="$tdydate" -v ip="$ip" 'NR>7 {print date","ip","$12,","$1,","$10}'
Any idea how the same can be retrieved on an AIX host? This... (1 Reply)
