Programming :: Get The Creation Time Of A Process Via Pid In C++
Mar 22, 2010Scenario: ( in C++ code)
I need a process A to be able to get the start time of process B. I have the PID of the process B.
I would have thought there would be a simple system call to make by passing in the pid of Process B, but I don't thing there is??!!
So my other thought is to create a script that will be passed the pid and either I can read the file creation of /proc/<PID>/stat or I could also parse the start time of ps on the <PID>. This script can be ran from the C++ code. My difficulty is capturing this information in the C++ code. If I run exec ( or system if not a script) I need the results in a program variable....not stdout.
My only solution is write it to a tmp file and read it back into the program variable. Seems rather arguious but a least it would work.
Background - I need to port Windows code ( GetProcessTimes(creationtime,...))

Mar 8, 2011i'm programming a small widget for a panel and need some information from my system. The command on the shell would be whoami to find out which user i am. This information is needed for my widget to set up the title of the widget, the information of the user will be retrieved out of the /etc/passwd (the code works just fine), but i don't know how i can get the information. One possibility would be to create a child process, call whoami with execlp(). But how can i retrieve the output of that process?

Programming :: Function Handler Is Called One Time Only Instead 2 Times If The 2 Timers Expires At A Time
Mar 2, 2011I am using Debian linux. I have 100 timers running. If a timer expired which will generate a signal and it was mapped to a same function handler. All the timers are mapped to one function handler. The problem is if the timer expires one at a time, the function handler called at a time. But if the 2 timers expires at a time, the function handler is called one time only instead 2 times. Is it possible to invoke the function handler as many times based on timer expirary happens simultaneoulsy?

Dec 7, 2009Consider the following code:
Code:

[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

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?
Programming :: Storing Grep Output To Feed Awk To Retrieve Entire Records Matching Variable
Jul 28, 2010I have two files :
FileA
prot1
prot5
prot9
prot15
[Code]....
What I need to do is to extract from fileB the fields containing only the strings in fileA.
I thought awk could do the job easily with :
Code:
awk 'BEGIN { RS = "###" } /'$variable'/' fileB > output
where variable would maybe be the output of grep from fileA. So can I store the output of grep in a variable to use it afterwards with awk ?
something like that:
Code:
result=`grep prot. fileA` ; awk 'BEGIN { RS = "###" } /'$result'/' fileB > output
but that doesn't work. I'm always getting the entire fileB.
The output of grep get stored in the variable, I verified that with echo. So there is something that I just don't get... It seems to me that the above line should work.

View 3 Replies View RelatedFedora :: Microcode - Boot Process Hangs At Startx Time
Sep 4, 2010Ever since the kernel update to 2.6.34.6-47.fc13.x86_64, my boot process hangs at about startx time. I boot cleanly at runlevel 3 in either this or the previous 2.6.33.8 kernel. If I execute startx from here (in either kernel), the system hangs at the same place. During the early troubleshooting, I read in another thread (250929) about installing xorg-x11-drv-catalyst, which I did using yum. This led to the failure of the 2.6.33 kernel; yum remove did not fix this. I have carefully followed the instructions in the fglrx HOWTO (updated a week ago by Hlingler) as they relate to a PAE kernel (including reinstalling mesa-libGL), and that fixed earlier difficulties. Hence, I felt I needed a new thread.
dmesg tells me
Code:
microcode: CPU0: patch_level=0x2000032
platform microcode: firmware: requesting amd-ucode/microcode_amd.bin
Linux video capture interface: v2.00
piix4_smbus 0000:00:14.0: SMBus Host Controller at 0xb00, revision 0
microcode: CPU1: patch_level=0x2000032
platform microcode: firmware: requesting amd-ucode/microcode_amd.bin
microcode: Microcode Update Driver: v2.00 .....
But the program itself reports
Code:
# microcode_ctl -h
This program is for updating the microcode on Intel processors belonging to the IA32 family - PentiumPro upwards (x86-64 included). It depends on the Linux kernel driver. The website urbanmyth.org/microcode (mentioned by yum info microcode_ctl) clearly indicates that Intel has taken over this microcodecode distribution, and suggests that it is no longer valid for AMD processors.
I found a reference to a kernel configuration flag CONFIG_MICROCODE_AMD (as a plausible subsititute for CONFIG_MICROCODE_INTEL) that possibly belongs in a script in /etc/init.d - but the above context leads me to suspect this is not true any more. In any event, those flags are not mentioned anywhere in my init.d scripts - in fact nowhere in the entire /etc tree. My microcode file exists, and is dated March 23. How do I get it installed? Or is this completely unrelated to my hanging boot problem, as suggested by the "platform microcode" line in the dmesg output? If so, where should I be looking?

General :: Process - Run A Script For A Specified Amount Of Time Before Stopping And Restarting
Jul 15, 2010Possibly related to this previous question, I would like to be able to run a task for a specified amount of time, then stop/kill it, then start it again. Specifically, I run the Folding@Home application on my Linux workstation. Periodically, it will have trouble logging-in to the home server, and will sit idle for a long time, but not release memory/resources it has claimed (yes, I realize this is likely a bug in the tool, but I can't fix that currently). Typically just the act of killing and starting the tool will allow it to check-in again. So, I would like to be able to run something like:
run_for <time> ./fah6
Does such a tool exist, or should I write a wrapper than nukes the fah6 client after, say, a week and restart it?
General :: Process Is Very Timely As Converting Loads Of Avi Files At A Time
Oct 12, 2010I'm rather new to linux, and I have a dedi server. I know how to browse, install, remove etc, all the basics needed to use it. I've installed flvtool2, memcoder and ffmpeg, and at the moment im converting avi files in to flv. Im then passing metadata using yamdi.
However, this process is very timely as im converting loads of avi files at a time.Im looking for a script, or a way where I can execute one command/script and which will convert all files in the directory I specify, then run those converted files through yamdi.Im guessing it would be some sort of loop, and then changing for each file?
Fedora :: Way To Reduce Running Time / Memory Requirement Of Update Process?
Aug 14, 2010I have an Acer Aspire netbook with 1GB RAM and 1.6 GHz dual-core 32-bit x86 chips. The KPackageKit / yum / rpm chain is running too slow for me. In addition to the time required to download any new packages or updates, it seems to require at least one full minute of processing time to install each package, update, or bug fix, no matter how small. Another full minute is consumed for each package in "cleaning up."Running yum from the command line takes nearly the same amount of time.During this time, I cannot run any other applications without severe thrashing. It seems that a full gigabyte of memory is in use with some 100M swapped out to disk.
Is there any way to reduce the running time and memory requirement of the update process?While not updating or installing software, I do not normally run out of memory (i.e. begin thrashing) until I have about a dozen browser tabs open, or the like.
General :: Find Out How Much Time An Already Running Process Is Spending In User And Kernel Spac?
Jun 8, 2011I am currently struggling with one of my tasks.I was asked to find a way how to determine how much time an _already running_ process is spending in user and kernel space.E.G. <some tool> <pid>[Control] + [c]<pid> spent 12.1 seconds in user and 1.52 seconds in kernel space.Does something like this exist? Basically I guess I am looking for something similar to time, except that the process is already running.So..a) Is there a tool which fulfills this task?b) Is there a way to write your own software which does the job? Is it even possible to code something I am looking for?I recently found strace -c -p <pid>, but well, this is not exactly what I was looking for.
