In Windows environment when I used Borlan for C/C++ compilation, I was used to find the the scope/definitions of the methods/classes by pressing
Code:
ctrl + F1
when the cursor was hovering on that method/class. How can I find the scopes/definitions in the GNU/Linux?
Code:
//atoi.cc
#include <iostream>
main(int argc, char* argv[]) {
float var_float = atof(argv[0]);

I am currently working on "Creation of Postmortem data logger in Linux on Intel architecture. Its nothing but core utility creation. how the signal handlers for various signals(SIGSEGV,SIGABRT,SIGFPE etc) which produce core dump upon crashing an application internally implemented in Linux kernel. I need to re-write these signal handlers with my own user specific needs and rebuild the kernel. It makes my kernel producing the core file (upon crashing an application) with user specific needs like showing registers,stackdump and backtrace etc.

I work with python and I use emacs as my IDE tool. I have been running Debian Squeeze (6.0.9) for some time now with emacs 23.2.1 and ecb 2.32. I am able to access my python methods in the ecb-methods window with no problems. However I recently upgraded my desktop to Debian Wheezy (7.5) running emacs 23.4.1 and ecb 2.40 but I have lost access to the methods in the ecb-methods window. The window is just empty while the others (directories, sources and history) are all populated. I have a second laptop which I decided to upgrade to Debian Jessie, however Jessie recommends emacs 23.4.1 which is running with ecb 2.40 also. The result is the same as on Wheezy.
I have used the ecb menus and googled for a solution or even just a mention that such a problem exists but have come up with nothing. Either I have a unique situation here or am doing something really dumb.
I would like to upgrade to Wheezy or Jessie but I need access to methods in the ecb methods window. How to keep my upgrade and see the methods in the methods window of the ecb system ....
I was playing with top to understand ram memory usage of every thread but i am in trouble with some basic questions:
- what difference is between 'thread' and 'process'?
- what does 'virtual image size' means, and Resident size, Shared Mem size, Code size, Data+Stack size, Swapped size? I thought that the only important field is 'Memory usage', but it is represented as a percent value...
I have googled a bit, but nothing really helped me. before opening top i thought that memory is divided in several pages by every process/thread (?) and that this occupied memory would be counted as 'used memory', and nothing else.

I'm trying to math all class references in a C++ file using grep with regular expression. I'm trying to know if a specific include is usuless or not, so I have to know if there is a refence in cpp. I wrote this RE that searches for a reference from class ABCZ, but unfortunately it isn't working as I espected:
grep -E '^[^(/*)(//)].*[^a-zA-Z]ABCZ[]*[*(<:;,{& ]'
^[^(/*)(//)] don't math comments in the begging of the line ( // or /* )
.* followed by any character

Well, I can get patterns like this:
class Test: public ABCZ{
class Test: public ABCZ {

I just recently rebuilt my RHEL 5.3 system using MONDO onto differnt hardware. The tool worked GREAT on my 32 bit system. The only problem I am having now is that since this system was built as a clone of another system on different hardware, it copied over the network definitions as well. Not good!!! So although my system is up, I can't get it on the network because it still wants to use the original NIC's that were on the other system. How can I blow away all network hardware definitions and tell the system to go out and re-discover so that I can configure them with the nessasary network information.

Recently, my fraternity decided to use our LAN to stream media to our various bars, lounges and ballroom. Some of our playback devices, including an iPhone and a laptop, broke during a party, which is why we decided to have portable devices replaced with sturdy, interchangable and fixed hardware.
As this is going to cost some money and effort, we had better make a fully thought-through plan, which I am in charge of. Still, having never organized a project of any measurable magnitude, I would rather have this plan commented on here.
So far, I am planning to buy one central PC (2GHz, 512 MB RAM) acting as a server, and four identical PCs (1GHz, 256 MB RAM) acting as clients. The former would a) provide local files, stored an an external encrypted hard drive, and b) act as a NFS and SMB client to private systems in the same LAN to incorporate (and forward) data stored on those (as to provide one central point to change the configuration for their use). Futhermore, it would host /etc, /usr and /home of the individual clients to provide that at all times, the same software and drivers are used on all of them. The clients then would mount /etc, /usr and /home from the server, alongside with the both the directories on its external HDD and the ones it had itself mounted from other PCs. Each of them would have to be able to play back music, video files and terrestrial TV from a USB stick, with at most two of them doing so at a time.
Is this a realistic scenario? I so, would you have any recommendations for changes and could you point out pitfalls? The whole lot would have to be rather secure, as usually, there are lots of people coming and going, and we don't want our private data corrupted. If not, where did I go wrong? How would you yourself build a system like that?
And last, what software would you use? Is there a window manager which would be able to act solely as a means to display the three icons needed for TV, video, and music, and make it impossible to tamper with the system? And what programs would you use for playback to ensure maximum performance?
P.S.: Not that I'd suspect so, but is there a german lawyer present? Provided the individual files we play are in our legal posession, this is a legal scenario, isn't it? There would only be friends and other frats present at any public display.
Are there any tricks/sites/methods to use the linux man command in a more convenient way? I love commands in terminal but for some strange reason I preferred to type man in firefox then in the terminal. The output is so long and I have to scroll forever to find what I need. Also the lack of example is a headache.

Where are the definitions for C library functions located? It was just recently that I realized that header files don't actually define any functions, they merely include their prototypes.
For instance, stdio.h includes the following line:
Code:
This just means that the definition of printf() is located in another file. What file? Is there some kind of default shared object file that is automatically included during compilation?
I have somehow managed to wreck the definitions /paths for my Home and Desktop. If I click on Places I now have a "Home Folder" displayed as "Open Your personal Folder", a "Desktop" displayed as "Open the contents of your Desktop in a folder" and a second "Home Folder" displays as "Open '/home/ian'"....and they all point to the same folder which is my personal user file "ian". This is kind of OK except that every file I have now gets displayed on my screen because "Desktop" has a view of these files. Is there any easy way to reset my file directory ? or do I have to backup my files and reinstall Ubuntu.

i've just started to learn about functions in Bash scripting. I'm able to set the functions and execute the commands correctly. However, if my_var is set in the first function and then later in the script in the script the 2nd function is called, it doesn't seem to remember my_var and quits (at least i suspect this is the problem).
Here's my code (it requires yad available via webupd8. org). My specific problem seems to lay in line #27 where if we view the changelog and then exit that window, it returns to the "main" function but any subsequent commands cause a crash. Is this because of the get command on line #29? It's presumably now out of scope after calling menu on line #25?
