2^64 is still far from the "infinity" my ram/hard drive can handle... First I wonder how GMP works with memory/processor since it does some kind of shady optimisations... I was also wondering if there is a way of storing an integer (unsigned, it's easier) on an arbitrary number of bytes. For example, on 50 bytes, I would have a cap of ...
I perform some calculations, based on the result, I would like to either use a short int or int for some type of data for the remaining program. Can (/How can) this be done sensibly in C or C++? I don't really care about the amount of memory used (i.e., 2 or 4 bytes), my primary aim is to access generic arrays as if they contained data o...
I have a server and a client. The client is capable of sending out various types of IPC requests. What are some proven approaches/frameworks for a generic timeout handling that can accomodate each type of request? Ideally, I would like to have: different behavior for handling timeout of different types of messages on client side, repo...
I'm in great need of a way to dig through potentially huge amounts of CGI supplied POST data. With reading the GET data it's no big deal, as I can just re-request the QUERY_STRING environment variable as often as I want, but with POST data which is supplied via stdin. I can only read it in once and have to store it somewhere. My curre...

I am trying to read the contents of a file (which contains both 'standard' text and 'binary' data). I then need to take that character (standard or extended ASCII) and get the corresponding Decimal (int) ASCII value. I am having a heck of time getting it to work correctly. Here is a snippet of the code to help show what I am currently...
I want to initialize an double array with size 200, and its value is from 0 to 199 from index 0 to 199 in c++. i know i can do it by a simple For loop, but is there a way just to initialize the double array like this? Thanks ...
I have programmed in c and I know about data structures and algorithms, but It has been a while since I programmed in c. I forgot things like how function pointers and some advanced stuff in c work. I want to try graphics programming using sdl. my question is how much of c should I know (for example should I know function pointers) befor...
Hello, Why is it that the following code does not print the same value each time it is run? Is there something that I overlooked? Thanks. #include <windows.h> #include <stdio.h> #include <winhttp.h> #pragma comment (lib, "winhttp") int main(void) { DWORD dwSize = 0; DWORD dwDownloaded = 0; LPSTR pszOutBuffer; BOOL bResults = FAL...
Is there any option to zip the file using C programme without using any external application (like Zip..)? ...
Background: I am receiving a array as char* as a part of socket session. Now we have to match the Tokens (HTTP headers) out of it.Code here is that we have created a UBYTE* and getting the value from the char array after typecasting with UBYTE. Later same UBYTE pointer we are passing to other function which accepts char* after typecastin...
I'm trying to create a matrix data structure in C. I have a struct and have a two dimensional void pointer array (size is dynamically defined at the heap) for the cargo part(data) in this struct. Given a column index, I want to get the values of this column in a one dimensional array. It is easy to this with one for or while loop. But i...
I am trying to teach myself C from a python background. My current mini-problem is trying to do less hard-coding of things like array lengths and allocate memory dynamically based on input. I've written the following program. I was hoping for suggestions from the community for modifying it in the following ways: 1.) Make first and ...
Is there any function to import a C library (.so) file in the Solaris operating system? In Windows I can use Win32::API, how about Solaris? Thank you. ...
Hello guys, My application continuously calculates strings and outputs them into a file. This is being run for almost an entire day. But writing to the file is slowing my application.

Hi I have started coding a packet injector and read up a bit on what one has to do. One thing I'm wondering though is when I create the IP header the h_source and h_dest fields should contain the mac address of the sender and receiver. Do I have to do this and is there a quick way to find out the mac address of the destination? Let's sa...
In C/C++ under Linux, I need to allocate a large (several gigabyte) block of memory, in order to store real-time data from a sensor connected to the ethernet port and streaming data at about 110MB/s. I'd like to allocate the largest amount of memory possible, to maximise the length of data sequence that I can store. However, I also need ...
