I am using qcheck=all while compiling my makefiles. When I am running the binary file generated then it is converting integer to a double value For eq: 612 to 612.0 Can anybody help me to know the reason why?
Is there any command that I can use for getting the memory usage and where can I find the executable of either Gnome/Source Monitor which i can use for finding the memory usage
Is there any command that I can use for getting the memory usage and where can I find the executable of either Gnome/Source Monitor which i can use for finding the memory usage
I want to get the memory usage of my process in Suse. I have used some command like top,ps v but the they give the percentage of memory used while I want the amount of memory used Is there any other command that can give me the amount of memory usage for my process
I have taken the opensoruce from ~wagnerr/ConfigFile.html for reading configuration file. It perfectly works fine with gcc 3.2.3 and it fail to compile with gcc 3.4.3 on RHEL 4
Which brings up a question to a TS: why your libraries are separate?
Actually we have a project in which we are using js open source files making it a lib and we have a seperate component lib. Now they are certain files which are dependent on each other. We cannot combine it either. so we have seperate libs
In Suse I have got 2 libs which I have to use to link with my source files but they are interdependent on each other. Means if the 2 libs are A and B than
A is dependent on B and B is dependent on A
In that case what should be the order in which we link the lib so that we dont get linking error Or can there be any other solution
const int j=18;
int *k= (int)&j;
*k=110;
printf("Data: %d -> %d; %d : %d-> %d\n", &j, j, k, &k, *k);
this well return for me Data: 2280676 -> 18; 2280676 : 2280672-> 110 but if i remove "const" well i have Data: 2280676 -> 110; 2280676 : 2280672-> 110 this work.
But how can same memory address have two int ( 18 and 110 ) Can somebody tell me how this are possible?
I once made a small kernel just for pure fun. It was very poor and I can really advise you on just one part of it. > Memory management You can use parts (or whole) code from this site: http://www.fourmilab.ch/bget/ I believe it's GPL, find out for yourself.
You can also try GeekOS code for some tips on implementing. Here's a link to Sourceforge site: http://geekos.sourceforge.net/
Hope it helps.
I liked the projects and were very helpful but I felt they are a bit advanced.Can you provide me some links were I can get basics of OS and slowly advances to higher level Thanks
I am starting to learn C basic OS Concepts and I have to code them using C. Can anyone suggest me some good links where I can get basics of the complete OS Concepts like (process,IPC,thread,sheduling,File management,Memory management, Security) I have got good idea about the concepts but I am very poor in implementing those in C code So what I am looking for is code for the above concepts
1. Can I compile a single program than runs on both 32 and 64?
2. I have a 64bit Debian Linux and tried to compile using -m32 but returned error. I'm probably missing some package. Any ideas?

How to: 1. Buffer output ? 2. Get its size ? 3. Print the buffer ?
#include <stdio.h>
int main(void)
{
printf("Tons of printf lines\n");
// 1. Somehow buffer the output up until this point
printf("The size of the buffer is: %i\n", SIZEOFBUFFER); // 2. Get and print the size of the buffer.
printf("Here is the output:\n\n%s", BUFFER); // 3. Print the buffer.
return 0;
}
What is SIZEOFBUFFER and BUFFER in your code and can you explain clearly what you want
If you want to play a .wav file you can use mfc program in vc++ to do so Make a project in mfc and use some of there API's like sndPlaySound or PlaySound The same you can put in an array if you want
Please mark the thread as solved after it gets solved It helps the onlooker and the members to know which threads are solved ad they can look into those problems if they have a similar query.
But in many occassions it happens that even after the problem is solved the thread creater doesnot close the thread as solve. This should not be done and we should make an habit to always close the thread after our brilliant forum members solves the problem.
I have the runtime. What i am trying to do is that a server is running in my PC. When a client requests than with my program I have to check that does his PC has the runtime library or not. For that there should be a place where some regitery files of VC ruuntime is present which i can query.
I am running a program(client) that creates about 20000 sockets. After closing this exe when I again want to run than some of the sockets still remain alive and are not closed. Is there any mechanism that I can close these socket just after my exe terminates.
I want to check by a c program that in a system Microsoft Visual studio Runtime is present or not. The system might not have complete package of Microsoft Visual studio but we can run a c or c++ program using Microsoft Visual studio Runtime(MVSR)
I want to know that is there any place where any registry files of MVSR are kept which I can search from my program that in a particular PC MVSR is there or not.
what is the time that select func in socket programming waits before continuing. Like till how much time it can receive msg from diffrent clients before proceeding to serve the request.
One more question. Can we send 500 messages from 500 diffrent clients at the same time to a server and the server will be able to process all of them. If yes how.
poll and epoll are like select. While through select you can establish only 1024 connections using poll and epoll we can establish 200,000 connections In places where we need more no. of socket poll and epoll are prefered Though they are only available at Linux.
