These two functions are both infinite loops, and the programe hangs once called in the same thread. gtk_main(); ... pcap_loop(adhandle, 0, packet_handler, NULL); When I click the "start" button,I want pcap to start working;And if I press the "stop" button,pcap stop. How do I create a child thread and run pcap_loop(adhandle, 0, pack...
When I work on someone else's code, I tipically need to abuse of grep in order to find data types declarations etc, and this usually makes me confused. I'd like to have some tool which analyzes the source code and produces some graphviz-like drawing and allows me to follow dependencies. Also I've found this on the internet, but I think...
Hi. I've sort of just finished a mandatory task at school, and I'm about to deliver it. But then I came across something that was unfamiliar, header files. :( What I've got: test-program.c task_header.h function1.s function2.s function3.s function4.s test-program.c: #include <stdio.h> #include <stdlib.h> #include <string.h> #incl...
Hello everyone! So i have this issue : i am declaring some extern global variables in my C program. If I don't use the -c option for gcc, i get undefined references errors. But with that -c option, the linking is not done, which means that i don't have an executable generated. So how do I solve this? Here is my makefile (written thanks...
I'm sure you (pros) can identify the bug's' in my code, I also would appreciate any other comments on my code. BTW, the code crashes after I run it. #include <stdlib.h> #include <stdio.h> #include <stdbool.h> typedef struct { int x; int y; } Location; typedef struct { bool walkable; unsigned char walked; // number of...
What I have understand about passing arguments to main() from command line is that argc has a minimum value of 1 and argv[0] will always have the program name with its path in it. If arguments are provided at the command line, then argc will have a value greater than one and argv1 to argv[argc-1] will have those arguments. Now a paragr...
My executable needs zlib1.dll to run, and I need to keep them together now and then. How can I merge it into the executable to save the trouble? I'm using cmake to build the executable. UPDATE zlib1.dll is not directly included by my programe,but required by libpng14-14.dll(one dll of the gtk bundle) ...

I'd like to write a DLNA server in Cocoa for the Mac. Are there any libraries for speaking UPnP/DLNA in Objective-C or C? Failing that, where is the spec for DLNA so I can write my own? ...

Hi! I'm trying to make a C# program which will use a C .dll (unfortunately, the .dll doesn't have good documentation) to access a smart card. One of the functions of the .dll uses name of the reader as argument. My problem is that I don't know how to get the name. After looking for answers I found something similar to what I need in an...

How do I define and call that function from the shell's command line? a#include "smallsh.h" /*include file for example*/ /*program buffers and work pointers*/ static char inpbuf[MAXBUF], tokbuf[2*MAXBUF], *ptr ...
I just wanted to try out some shaders on a flat image. Turns out that writing a C program, which just takes a picture as a texture and applies, let's say a gaussian blur, as a fragment shader on it is not that easy: You have to initialize OpenGL which are like 100 lines of code, then understanding the GLBuffers, etc.. Also to communicate...
Hello, I'm wondering if someone could offer me some tips on how to go about this. I have a MacOS X OpenGL game that is written in very portable C with the exception of the non-game-play GUI. So in Cocoa I set up the window and OpenGL context, manage preferences, registration, listen for keystrokes etc. But all of the drawing and proce...
Hello, This program asks for any row number. I want the program to loop a scan function if the user types anything else other than numbers.. My code is : do{ printf("Enter row number\n"); scanf("%d",&row); }while(row>='a' && row<='z'); but this code doesnt work .. I keep getting an error when typing in a letter. I tried man...
I would like to parse the menu structure for Gnome Panels (the standard Gnome Desktop application launcher) and it's KDE equivalent using c/c++ function calls. That is, I'd like a list of what the base menu categories and submenu are installed in a given machine. I would like to do with using fairly simple c/c++ function calls (with NO s...
Hello, I want to allow users to type the name of any .txt file to be read/written. This is my code : printf("Enter .txt file name\n"); scanf("%s",&fname); FILE *inputf; inputf=fopen(&fname,"w"); Problem is this method does not work (having &fname) as a parameter. I can imagine its because C needs "filename.txt" for it work...
So I am writing a simple Rock, Paper, Scissors game in C (it's for an assignment by the way, though the main thing is to learn sockets. Also, I suspect it will be due before I get a good answer). I have it setup as Rock=0, Paper=1, and Scissors=2. Is there an easy one-liner to determine who wins? I tried playing around with it on pap...
