Programming :: Function Successfully Called But It Did Not Run Device Properly?
Jan 6, 2010I have our own C written program code which is communicating with a third party C++ written program code to run a moving device. We have successfully communicated with the third party code with wrapper functions. (Thanks to member in LQ that helped me solved this.)Now, we tried to run some functions to move the device. I think it is better for me to attach the related code first. pro.c (The source code we used to run the device)
Code:
#include<stdio.h>
#include "wrapper.h"

Programming :: Destructor Called On Objects In Deque Without It Being Called Explicitly
Jul 13, 2011I feel there's a bit of a misunderstanding going on between C++ and me...My problem is that I have a deque of pointers to a class, and create objects then add them to the deque in a for loop. However, the destructor is called on the object as soon as the loop quits.
Code:
This prints:
Code:
Now, if I change the deque from deque<Test*> to deque<Test> then it works fine - I get:
Code:
However, I can't do this with my actual code, because I am creating a deque of pointers to an abstract class, so it won't let me instantiate the class. (This is all so that I can take advantage of polymorphism, and call functions on a set of similar objects without worrying what type of object I'm dealing with).
So, I suppose my question is: what is the correct way to create that deque of pointers to the abstract class? I don't seem to be barking up the right tree currently.
General :: Crontab - Schedule Job To Run Every Minute?
Apr 14, 2010I am setting crontab to run a script every minute irrespective of the current hour's value:
Code:
[root@localhost bin]# ls
sec.php showTime.sh
[root@localhost bin]# crontab -l
1 * * * * /root/bin/showTime.sh
[root@localhost bin]#
But it is not working. Does the line mean: "Run this script every day at hour:01"?

General :: The Directory Would Not Exist Until 'mv' Has Been Called As In?
Jul 3, 2011I want to copy a file from an old directory to a new directory and ideally I would like that the 'mv' command itself could create the directory for me in one step...That is to say that the directory would not exist until 'mv' has been called as in:Code:mv olddirectory/file.dat newdirectory/file.datso mv would create the directory 'newdirectory' in the above call....I am not sure if this is possible however, that is to say I think it may be necessary that the directory 'newdirectory' already exists before I make the above call to mv, as when I make try the above call when 'newdirectory' doesn't exist I get the following error:Quote:mv: cannot move `test1/4215/4215-001R.fit' to `test2/test.fit': No such file or directoryso to sum up, my question is:is there some paramater for 'mv' that I can change so that it will create the new directory as well as copy the file and if not, are there other commands that might do this?

General :: What Is It Called When You Move A PDF Window While It Is Loading
May 18, 20101. What is it called when you move a PDF window while it is loading and the window manager does not keep up with the image, (it gets all blurry when the window is moved?)Why does this happen?
2. Why is it that when a browser window is clicked to load a new address it won't always go to it. It has to be clicked again.
3 Why is it that sometimes IE is the only browser that will work on XP. FireFox and Opera will not load a page but IE will.
4 Why is it that Firefox on Linux sometimes everything inside the window is slow to appear. It has to be closed to fix it. When the contents does appear it is all at once.
5.Why is printing different things on Linux a problem. I have a lot of inconsistency with trying to print things from Evince. Some docs print and some won't. Copying and pasting is also a problem for Evince.Why?
6. Is there a way to have Linux Shut down after computer activity has stopped and not just with a timer. Lets say I'm trying to download something and I want it to turn off after it has finished with the down load.
7. Why are some Web pages biased towards Windows. I notice that some java scripts will only run right on Windows machines with IE. A lot of on-line forms are like this.
8. Can (MOVIES, PICTURES AND MUSIC) torrents be downloaded on Linux without risk?
9. It seams that Linux browsers do not keep previous web pages in memory so if you want to go back Linux always has to reload them from the server. Why is this?
10. Why is it that browsers sometimes won't indicate that the page has finished loading, "ever".
11. Why does Linux turn on the number-lock when loading its self?
12. Why can't the brightness be adjusted in Totem? There is a menu to change it but it does not work.
General :: Stop A Function Called In A Script?
Sep 30, 2010I made the following script:
Code:
#!/bin/bash
logErrors(){exec 2>/tmp/errorlogfifowhile truedocat /tmp/errorlogfifo |echo $(date "+[%Y-%m-%d %H:%m:%S]") Error: >/var/log/error.logdone}
logErrors
ls inexistentFile
exit 0
If I execute the script I see the formated error message in /var/log/error.log, as to be expected. After the script execution, I hoped "logErrors" was not executing anymore, but when, in another terminal, I call "echo something > /tmp/errorlogfifo", I still see the formated error message "something" in "/var/log/error.log". How can I finalize "logErrors" before the script ends? Or, maybe someone knows a better way to format and log the erros in a script.
I forgot to say that the file "/tmp/errorlogfifo" is a named pipe created by the command "mkfifo /tmp/errorlogfifo".

View 1 Replies View RelatedGeneral :: Displaying Graphical Output From PAM Called Shell Script
Nov 19, 2009Before I begin I would like to say that while I am not a Linix newbie, I am not a guru or even a regular user so don't assume I have anything more than general Linux knowledge. I am carrying out research involving virtualization and Single Sign On technologies and I need to display a Xen based virtual machine to the desktop before the user is logged in. This is for a demonstration system and I am trying to find a solution that involves the least amount of system modification possible.I found a PAM module that allows for the invocation of arbitrary shell scripts which would allow me to start and display the virtual machine in question, but when trying to run the virt viewer (or any process with graphical output) I am informed that the display cannot be found. Explicitly setting the DISPLAY env to :0 before running the command has no effect.
This is where my Linux knowledge runs out. I know that there has to be some way to connect to the X session being used by the greeter, I just don't know what that method involves. The shell script is running with root privileges, so it can access whatever "X credentials" are stored locally.
I will be thankful for any assistance this forum might be able to provide, but please do not suggest alternatives to displaying a VM for my SSO needs, and please avoid any solution that involves having to write my own custom greeter. If there is absolutely no way to accomplish what I am trying to do without greeter modifications definitely tell me, but I am a security researcher, not a Linux developer so I am looking for the easiest solution to implement, even if that solution is a gross hack.
