I am trying to take argument from command line ic a Cprogram an give that argument as an argument to a script file which is called in that C program.Is it possible for example:
my C program is:
#include<stdio.h>
#include<string.h>
#include<stdlib.h>
[code]....
I want to fill that blank with thevalue of argv[1] such that it will act as an argument for temp1.sh.
I have a new problem; i want to call a subroutine's fortran which have a function in the argument and the compilation ran properly, but when i execute the program this shows me an "Segmentation fault". This is my c++ program:
Code: //Main.cpp
#include <stdio.h>
#include <iostream>
[code]....
I'm trying to write a base script which will divide an argument by 10 and then use that argument in another program. Since my argument can be a floating point number, I used bc to accomplish this. Here's an example of a simplified version of what I have so far:
<code>NUM=$(echo "scale=25;$1/10" | bc)
#make sure the first argument was formatted correctly
if [ $? -ne 0 ]
[code]...
I read somewhere that you should not be reading config space to determine the irq value to pass as the first argument to request_irq(). What is the proper way to determine the value of the 'irq' argument before calling this function? Hope this is the correct forum. I don't see one for drivers.
View 1 Replies View Related(For function arguments): Scalar arguments are passed by value, which means that a copy of the argument is made for processing in the function, and changes to the argument in the function won't be reflected back to the calling program. Objects though, are passed by reference: any changes to them in the function are reflected in the calling program. What sense does this make? Why have they done this?

After some time the picture comes back, first with some ugly artifacts in it and then completely. I've found out by letting htop run in the mean time that during these time CPU usage spikes up to a 100%, I also identified the process causing it (see attached screenshot)
Code:

I am having some weird problems with calling commands stored in a variable (I need to do this to assemble a command with a bunch of parameters automatically and then execute it).Example code that will replicate the weirdness:
$ echo "hello world" > "test file.txt"
$ cat "test file.txt"
hello world
[code]....
I would expect the output to be:
hello world
What happens to the quotes? I have tried various combinations of single quotes, escaped quotes, etc, but it seems like quotes in a variable are not evaluated as quotes when that variable is executed.

I have found a weird behaviour on a linux application. A tty seems to get closed without calling close. The program is (very simplified) as follows:
Process 1:
configure_signals()
read_config_files()
create_threads()
wait(forever)
Thread 1:
fd=open(/dev/ttyXX)
usleep(a while)
config(fd)
I have spent quite a lot of time on this problem. It seems like the file is sometimes closed when reaching config(fd), but removing the usleep(a while) seems to remove the problem.

I tend to use commands like 'aptitude search $something' or 'dpkg -S /usr/bin/command' (some command/variable in both) or 'apt-file search $something' and all/or many of its brethen. I do run updatedb every now and then but that command is for the overall health of the system similar to tracker perhaps (but not running continously like tracker and the daemon).
What I'm looking for is, if there is a way to get the package list (installed and otherwise) updated aggressively so that whenever I use any combination of aptitude or dpkg I get better response from the system. From what little I understand, aptitude or dpkg or somewhere there would be some sort of index/database where the current state of package availability and system state would be recorded. If there is a way that this could be improved upon would be nice to know. If there is some experimental package or road which the debian folks are looking for in the future so this latency can come down.
