Programming :: Stop Semaphores In C?
Feb 26, 2011i'm writting a program, that creates semaphores and shared memory. It asks from the user to give anything to write in the shared memory. Now, i want this program to do this,not only once, but repeat, and stop as soon as the user gives the word "quit". i added a while loop, but i don't know how to stop the program.

View 1 Replies View RelatedProgramming :: C++ Failing To Pass By Value?
Jan 25, 2010I have a strange problem with a simple program. I have a container class that holds a pointer. I did this so I could use another container class that does several pass by value calls. I didn't want to be copying the object over and over again, so decided to build this simple container that simply copied the pointer in the copy constructor.
However, the pass by value call seems to be failing in a strange way. When the pass-by-value function is called, the program jumps into the copy constructor just fine and performs the pointer assignment operation. The program will copy the pointer value 0x20 (for argument sake) to the "this->base" location. Within the copy constructor, this has the address 0x28. Then when it jumps into the function, instead of pass by value argument being at 0x28 (as expected), it is at 0x36. Then 0x36->base has the address 0x28. Thus the base is now pointing at what was the new pointer container. At this point the data is corrupted and random things happen.
It seems that there is some strange assignment and double nesting going on. I really do not understand what is going on.
Below is some code. I have stripped away all the other code trying to isolate the problem. I have added comments explaining what my debugger is telling me.
Code:
using namespace std;
class paramPnt // Need to determine how order is tracked
{
private:
long order;

May 14, 2010what the command is for the System Tray, so thought I'd ask here. Note I am not asking how to put a system tray on the panel - I know I can add a notification area, but when I reboot there will be 2 of them, so this is not what I want.
I just need to be able to initialise it when it fails to load. Since my upgrade to Lucid, this has happened a couple of times, so expect it will happen again soon enough.

I am perfectly familiar with Windows but I haven't a clue with this one. Have found a post on this forum relating to this fault but I am afraid it was double Dutch to me.

Check your installation". I'm then taken to failsafe, where I login. When I try to run kdeinit4 from the command line, I get this error:

Ubuntu :: Log In Failing On Most Users
Aug 15, 2010recently logging in become a bit unreliable - i thought i was mis-typing the passwords but on closer looking the passwords were ok (faulty passwords produces "authentication failure) Using the correct passwords the screen blanks for a second and then returns to the list of possible logins. I cannot log in except as one of the children - could this be because their logins have been used less often and less recently Everything was working well and I have not knowingly changed anything except the passwords after the problems started in order to solve what i thought was a simple mis-typing problem
I can log in as the children but their logins obviously do not have permission to do much
I also have a bootable puppy CD Unfortunately I am also a total noob but determined not to backslide into XP because up to now Ubuntu has been fantastic

When the full install failed, I tried installing it within Windows and that also failed. I've attached the log from that attempt in this post (had to trim it down to fit the file limit though). I don't know if these are the same errors I was getting on full install as I didn't write those errors down...I can try again and post them if needed though.

Feb 1, 2010HDA1 is going to die, SMART says its well beyond dead, and I can tell the read/write times have gone up drastically.
I know I can use dd to copy it from a live CD.
1.) If I dd it to something.img, is there a way for me to "work" on the backup copy? Basically, I need to backup ASAP, but won't have a replacement drive for a while, so I'll need to be able to put the changes into the backup.
2.) When it comes time to restore, if I dd it to a larger drive, is there a way to take advantage of all the extra space? I assume I can dd it over and the MBR & Partition Table will go with, so I can use something like gparted to grow the partition to the drive size?
Or is there a better way to make a backup?
