General :: Sending Signal From Child Process To Parent Process?

Sep 8, 2010

Code:

#include <stdio.h>
#include <unistd.h>
#include <signal.h>

[code]....

Description of what the code does or what i intended to do:

1. Created a child process from parent process using 'fork()'

2. Sent a signal 'SIGALRM' from child process to parent process using 'sigqueue' function.

(The Third parameter of 'siqueue' function contains the message (message msg) which the child process wants to send to the parent process.'msg' is a stucture instance containing a) pid of child and b) string) 5. Print the 'msg' sent by child process inside the signal handler function 'sig_action_function' of the parent process I am getting some junk value when this line is executed

Code:

printf("%d
",msg->cpid);

I expected to get the pid of child process, which the child process sent to parent process through the signal.

General :: Process Scheduler A Part Of Process Queue?

Aug 12, 2010

as we all know Process Scheduler does Process scheduling and its a process as well. I was just wondering that if this happens then the Process "Process Scheduler" should be a part of Process queue as well.

So if there are 5 process are there in Process queue & process scheduler is administrating them then since its also a process, once it puts a process under RUN state it should itself go inside queue because at one instant only one process can get executed on a processor. This is quite confusing for me. Please help me out. I tried to search on this but could not find any relevant topics.

I've been running my shellscript for about half an hour now. It's taking longer than I thought to process all the data. I have the process ID of it. Is it possible to save the process and log out then log in and continue the process? I know how to pause a process using kill -pause pID and continue it using kill -cont pID. But that only work if you don't log out after pausing it.

Programming :: Under Which Circumstances A Child Process Creates Another Child Process Using Fork

Dec 7, 2009

Consider the following code:

Code:

int main()
{
int i=0;
pid_t pid;
for(i=0;i<2;i++)

[code]....

I get the following output:

Parent: chid_pid=4356 i=0 parent's pid=4355
This is child 4356 i=0
This is child 4357 i=1

[code]....

I can observe instead of two children(as I expect) processes there are three. This is because child process 4356 creates its own child. Why all the messages of the type "This is child X i=Y" are concentrated one under another? How exactly fork works? Is affected by the fact that I have a dual-core processor?

General :: How To Tell If Process Is 64bit

Dec 21, 2010

Given the pid of a process that's running on a x64 linux, how do I tell if it's running a 32 or 64 bit binary? I can look at the binary it's running out of 'ps' and do a file on that but I was wondering if there's a way to tell by looking at /proc/ or something like that.

General :: Where Does Netstat Get The Process Name

Jun 25, 2011

I am developing a node application and there is an option to set the process title (process name). This only sets it in some tools (like ps and top), but not in htop or netstat.

I found this article that explained how most applications do it, but it doesn't change in netstat.

That lead me to wonder where those programs are getting the process name. Would they be getting it from /proc/##/cmdline? (## being the PID of the process)

I figure messing with things in /proc is a bad idea (and probably not possible), so if this is where those programs are getting it, is there a way to change it?

General :: Process Of Encrypting RAM While Still Using As RAM?

Jun 21, 2010

From previous post I have a netbook from work that I have Debian Squeeze running on and did a full disk encryption (minus the minimal boot loader in /boot) in case it gets stolen. However, with a laptop/netbook it has a battery and I believe the encryption protocol (LUKS - correct me if I'm wrong) uses RAM to store the decrypt key. So if someone is quick they can dump RAM and analyze it until they get the key. Or even if the key is not stored there they could dump RAM which would have recent files cached unecrypted.

Is there an easy process of encrypting RAM while still using as RAM? What I mean by that is I know you could make a ramdisk sort of like how Live CDs do and encrypt that, but at best (that I know of) I can only mount it as swap space.

General :: %CPU Too High For Process?

Mar 4, 2011

I am using centos 5, Kernel 2.6.18-53.el5. I am using 2 quad core processor with 4gb of ram

I am trying to figure out the significance of %CPU in the ps command.

My astreisk process %CPU is very high at the moment, at 115. I want to know if it is a cause for concern? If I do a top then the load of the box is very low.

Code:
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 2872 115 1.4 628664 58372 ? Sl 14:56 190:30 /usr/sbin/asterisk -f -vvvg -c

General :: CPU Usage Of Process

Jul 15, 2011

I am currently writing a JAVA script to monitor certain unix processes through JConsole. Upon having lots of trouble with runtime.exec, i decided to bypass the top/ps command call and just get the information straight from /proc/*pid*/whatever.Now i can pull back any information from any of the files I want, and the current way i determine the CPU usage of a process is as follows:Add the UTime and STime of that process from /proc/pid/stat then divide my pidCpu by UTime + STime + NTime from /proc/stat, then multiply that by 100, should give me the % cpu usage a process is using, right?Theory being if I get the jiffies assigned to my process, I can divide that by the total jiffies the cpu assigns.

However, my results seem to vary from the ones gathered from top and ps. What am I doing wrong?
