Programming :: Internal Working Of System() And Evecvp()?
Feb 17, 2010system() and execvp() both work by creating a new process. Question: Do they create new processes by internally calling fork() or there is some other way ?

Ubuntu :: Internal Disk In A Running System Usb-booted System Does Not Result In The System Detecting The Disk
Feb 27, 2011My system decided to crash on me, hard. It was humming along happily for about 2 months and now doesn't boot. If I boot from hard-disk, I get grub. Launching the first kernel choice hangs. I thought maybe the install was corrupt, so I booted from usb install disk. The usb hdd didn't boot; something about an error trying to access /dev/sda . Unplugging the internal disk and plugging in the usb install disk does result in the system booting. Plugging in the internal disk in a running system usb-booted system does not result in the system detecting the disk.
How do I know if the disk is physically broken? This seems unlikely since it does manage to launch grub consistently. Or is this still possible? How can I try to mount whatever is left? The usb install disk doesn't even list the /dev/sd*. Any pointers on how to reformat the drive if it's not being mounted?
Programming :: Ptrace System Command Not Working Properly In X86 Platform
Apr 20, 2011basically in the child process iam just calling the ptrace(PTRACE_TRACEME, 0, NULL, NULL) system call but if add this stsyem call rest of the code not working properly. i found the reason basically what happening is when we have ptrace() system call its printing the same variable 3 times i.e its not executing it 3 times but just it is printing 3 times .iam just wondering how it could be possible.

Dec 10, 2010I have the following code:
Code:
#include <stdio.h>
#include <stdlib.h>
int main() {
system("ps -ef | grep myprocessname");
return 0; }
When I run this program it outputs the following list of running processes:
Code:
root 10279 10275 0 13:02 ? 00:00:00 myprocessname myvar1=value1 myvar2=value2
root 10341 10337 1 13:02 ? 00:00:00 myprocessname myvar1=value1 myvar2=value2
What I want to really do is instead of writing the output to screen I want to read the output and parse the various values value1, value2 etc. What is the best way to do this?
Fedora Hardware :: Internal Mic Not Working In 15?
May 28, 2011The internal microphone of my laptop Thinkpad T400 does not work after the new installation of fedora 15. I was trying to use it in SKYPE and could not get any sound recorded at all. However, when I tried arecord, sound is recorded, but is extremely low and not clear with lots of noise.The sound control seems to be different from before. Now available settings are
Code:
None
Analog Stereo Input
Digital Stereo Duplex (IEC958)
[code]....
And the 'Input' page seems not bad because I can drag the Input volume. However, the 'Input level' is empty, or only 1 bar even I drag the 'Input volume' to maximum.Analog Stereo Output and Analog Stereo Duplex (the one I am using) are the two give me output sound. But none seem to work with my internal mic. I haven't tried an external mic, though, because I do not have one.There seems to be no more "advanced volume control" that I used in Fedora 12. Also, there seems to be no more ALSA devices or PulseAlsa devices?
'#arecord -l' list my device as
Code:
Intel [HDA Intel], device 0: CONEXANT Analog [CONEXANT Analog].
how to solve this. For example, is there a way to get those ALSA settings back (well, I do not really understand what ALSA is and how it works but it did work when I had Fedora 12)? I do have a lot of packages named 'alsa*' installed.

Jan 14, 2010I have a SuSE server (sorry but no idea what version of SuSe it's running.. I'd take a guess at 10.0) on a network with several other SuSE servers. They are all able to be SSHed externally as well as internally and all have their local firewalls disabled. I just had to reboot one of the servers and it is behaving quite strangely. I am able to SSH in and out of it externally, but can't SSH in and out of it internally.
When trying to SSH out internally I get the message:
"ssh: connect to host *.*.*.* port 22: No route to host"
When trying to SSH in internally I get the message:
"ssh: connect to host *.*.*.* port 22: Connection timed out"
Using ssh -v doesn't give any more useful information.
I have double checked that the IP is correct and that the internal firewall is disabled etc. The external firewall hasn't got anything that would prevent it (and shouldn't be an issue anyway as it's an internal only problem... SSH externally works fine). Also, it might help to know that I have the same problem with ping. I can ping this server from an external system, but not from an internal one.
Ubuntu Multimedia :: Internal Laptop Mic Not Working In 10.04?
May 24, 2010I have been going crazy with this maybe someone can help me out. I realized that in 10.04 my internal mic on my Asus G51VX does not work.
I have already upgraded my ALSA Drivers using the latest 1.0.23, and in alsamixer it shows the iMic and Capture devices correctly, however in sound recorder and in Skype I get nothing but a low hissing sound. I believe this is a pulse audio problem and not ALSA since I didn't have a problem in Kubuntu 9.04 using ALSA which I had previously to this.
In sound config pulseaudio shows that there is only one input and one output device which I figure should read 2 input devices since there is also a mic jack on the laptop. Either way it is really annoying not to have use of the Mic.
Device is INTEL HD AUDIO ALC663
Simple mixer control 'i-Mic',0
Capabilities: pvolume pswitch penum
Playback channels: Front Left - Front Right
Limits: Playback 0 - 31
Mono:
Front Left: Playback 31 [100%] [12.00dB] [off]
Front Right: Playback 31 [100%] [12.00dB] [off]
When I turn the i-Mic on I can hear the echo of myself coming out the internal speakers but it still won't record anything even with the Capture control on and at full volume.
Ubuntu Multimedia :: Gateway Internal Mic Not Working
Feb 12, 2011I've got a Gateway CX2724. The sound works perfectly out of the speakers and headphones, but I can't get the internal mic to work for the life of me.
I asked around on other threads and tried a few modifications to /etc/modprobe.d/alsa-base.conf and none of these get the mic working when appended:
From the ALSA-Configuration instructions
Code:
options snd-hda-intel model=ref
Ideas taken from this thread
Code:
options snd-hda-intel probe_mask=1
Code:
options snd-hda-intel model=test enable-msi=1 probe-mask=1
This also doesn't work (modified from this thread.)
Code:
options snd-hda-intel model=ref probe_mask=1 position_fix=1
This also doesn't work (from "Extra Hints to get sound working.")
Code:
options snd-hda-intel model=laptop position_fix=1 enable=yes
When I use alsamixer to turn "mux" all the way up and have my headphones plugged into the microphone jack (don't have an external mic... ) in the front of the computer, I am able to record things but the volume is greatly muted. Perhaps the external jack is set to default for the microphone instead of using the internal mic?
I also have the output for alsa-info.sh if you want it - this was mentioned in the alsa configuration file (/usr/share/doc/alsa-base/driver/ALSA-Configuration.txt). Info about alsa-info.sh here.

Programming :: GDB Internal - Error Using Backtrace?
Jun 16, 2010I have submitted the following to Bugzilla as well. I have a Fortran routine with a C signal handler. When a signal is caught, the signal handler calls gdb with a script argument to the system() call to output a backtrace. When I build the fortran file with the -g option, run the program, and send it a signal,I receive the error message "stack.c:295: internal-error . Without the -g option the error message does not appear but as expected I get limited output in my backtrace. Below is a description of the environment in which the bug is experienced, output from gdb showing the bugs occurrence, as well as source code and a Makefile to reproduce the bug. The problem occurs in gdb 6.8 but I have seen the same results with gdb 7.1

Ubuntu Installation :: Swap The Internal HD Out To A New System?
Jan 29, 2010I have an existing Ubunto 9.10 install sitting on a 500 GB SATA drive that was sitting in my second SATA port. I'm trying to swap the internal HD out to a new system that has a 500 GB SATA drive with Windows 7 on it as the primary drive, in SATA port 0. When I configure BIOS to boot from my Ubuntu drive, I just get a flashing cursor on the screen and no Grub bootloader like I was before.
Does this mean Grub isn't on my Ubuntu drive? Should I install grub on both my Ubuntu drive's MBR AND my primary Windows 7 drive's MBR, or only one of the other. The instructions I've been reading don't specify which drive to reinstall Grub on and which drive I should boot from, so I'm confused. How do I get it so that Grub acknowledges my Windows 7 install on the primary drive?

Ubuntu Multimedia :: Sound Is Not Working (Both Internal Card And XFi)
Sep 25, 2010I've spent the last couple hours trying to figure out how to get my SoundBlaster XFi card working, but somehow in the process seem to have now also broken my on-board sound which when I first installed did work. I have no idea how as I hardly touched anything.Both cards are recognized in Sound preferences, sound is not muted there nor in Alsamixer. But neither produce any sound at all now.
Searching around the forums it seems that as of now my XFi should, kind of, work out of the box, but I've had no such luck.I'd really like any advice possible on getting my XFi with headphones to work in 10.04, but if this can't be done I'd atleast like to find a way to fully reset my sound setting so my on-board will work without having to wipe this partition and reinstall - there Must be an easier solution than that.

When I click open alsamixer, the boxes for Front Mic, Mic Boost and Beep are empty. When I go to Preferences => Sound => Hardware I get a choice of Analogue Stereo input, output and duplex - as well as off. I go for duplex. When I go to sound => input, the microphone mute box in unchecked and the single volume bar is at a maximum. There are no choices - the one choice, Internal Audio Analog Stereo, is checked. As it's only once choice, it can't be unchecked.
