Where am I going wrong? #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <string.h> #include <curl/curl.h> #include <curl/types.h> #include <curl/easy.h> using namespace std; char b...
Hi guys, I know this may seem quite basic to geeks. But I want to make it crystal clear. When I want to use a Win32 DLL, usually I just call the APIs like LoadLibrary() and GetProcAdderss(). But recently, I am developing with DirectX9, and I need to add d3d9.lib, d3dx9.lib, etc files. I have heard enough that LIB is for static linking...

The goal is that for a variable that is an array of: typedef struct { GLuint vertex; GLuint normal; } indice_pairs_t; , we want to find all the pairs that are unique and put them in an appropriate order of appearance with unique pair indices intact. For example: if initial pairs are 2 3 6 7 6 7 4 5 (the 2nd and 3rd pairs are s...

Hello, gcc 4.4.3 c89 I am just getting started with log4c. However, there is very little documentation out there for how to get started with it. I am wondering does anyone know of any tutorials, articles on how to get started? Many thanks, ...
In C (linux) how will I be able to find out if the squareroot of a number is and integer or a floating point. I want to write a program using a function pointer which adds up all the Perfect squares upto the limit sepcified. ...
I have a buffer of raw values, say, void* buffer or better, char* buffer - a raw byte stream, for example, read from a file. I'd like the bytes in the buffer to be represented and displayed in several ways, for example, as a float, or as a long long in runtime. I'd ask a user for desired format string, for example, %10d, and pass the for...
hi for a project i need to send some data from c program to Perl program that both in running mode (Perl program in sleep mode and c program running, and c program sends data to Perl). i know that, can write this program by socket and shared memory but i have performance problem. i think shared memory is better solution, and how can i ...
Hi guys! My question is related to this other discussion. I'm trying to implement that algorithm using the dynamic program into a recursive call. Problem statement: Job j starts at sj, finishes at fj,and has weight or value vj. Two jobs compatible if they don't overlap. Goal: find maximum weight subset of mutually compatible jobs. ...
My understanding is that C++ reinterpret_cast and C pointer cast is a just a compile-time functionality and that it has no performance cost at all. Is this true? ...
A sequence point in imperative programming defines any point in a computer program's execution at which it is guaranteed that all side effects of previous evaluations will have been performed, and no side effects from subsequent evaluations have yet been performed. What does this mean? Can somebody please explain it in simple words?...
Hi. I am trying to make a simple HTTP server that would be able to parse client requests and send responses back. Now I have a problem. I have to read and handle one line at a time in the request, and I don't know if I should: read one byte at a time, or read chunks of N bytes at a time, put them in a buffer, and then handle the byte...
Can anyone explain me these pointers with a suitable example ... and when these pointers are used? ...
Hi folks. I'm developing some kind of mysql monitoring tool so I need interactive output like top command. Is there any lib that can be used for this? Thank you for you answers beforehand. ...
I have a small app that uses Lua linked as dll (not static). I want to load my own c++-written dll via Lua using package.loadlib (libname, funcname). For this purpose I need to export a function that follows the Lua's lua_CFunction protocol. Clearly for that reason I have to incorporate lua.h into my project and use Lua's functions to pa...
