Hi, I'd like to know if someone can explain me the solution to this problem: the code is: #include <stdio.h> #include <stdlib.h> typedef struct { int c[20]; int n; } t_coda; t_coda coda; void init(t_coda *coda) { coda->n = 0; } void add(t_coda *coda, int x) { if (coda->n < 20) coda->c[(coda->n)++] = ...

I have a system that needs at least 10 mseconds of accuracy for timers. I went for timerfd as it suits me perfectly, but found that even for times up to 15 milliseconds it is not accurate at all, either that or I don't understand how it works. The times I have measured were up to 21 mseconds on a 10 mseconds timer. I have put together...
I'm investigating using nvidia GPUs for Monte-Carlo simulations. However, I would like to use the gsl random number generators and also a parallel random number generator such as SPRNG. Does anyone know if this is possible? Update I've played about with RNG using GPUs. At present there isn't a nice solution. The Mersenne Twister that c...

I'm working through a chapter about iPhone audio and have come across a section of code that I can't make sense of: while (aqc.playPtr < aqc.sampleLen) { select(NULL, NULL, NULL, NULL, 1.0); } (Full code sample is on pages 163-166). From what I understand of the code the audio is being processed on another thread and the while lo...
I want to make a simple just-in-time compiler with c on Linux. How can I allocate memory such that I can write out raw x86 code to it and execute it as any other function? ...
I'm stuck on this. Currently I'm using: FILE *a = fopen("sample.txt", "r"); int n; while ((n = fgetc(a)) != EOF) { putchar(n); } However this method seems to be a bit inefficient. Is there any better way? I tried using fgets: char *s; fgets(s, 600, a); puts(s); There's one thing I find wrong about this second method, which is tha...
I'm doing a school project about maintaining a personal Database. but my tutors didn't explained the practice, they explained the theory(Data structures and such) not how to code in c. We where given a certain amount of tables, indexes and consults they wanted to solved and we are to program the data structures that run behind. I ch...
I was reading this article on MSDN "Managing Heap Memory in Win32" And in it they are explaining about a tool called ProcessWalker.exe In the article they explained that they can use this tool to explore the contents of virtual memory of any process. Does anyone know where I can download this tool from. Or maybe ProcessWalker might b...

I have a thread datatype in the interpreter implementation for a programming language I am working on. For various reasons, it’s a fairly common operation, to need to get the current thread (which is, itself, a pointer: a struct thread*). However, pthread_self(3) hands me a pthread_t, which is an opaque type; on some systems, it seems t...

Hi all, I just write a procedure to decompose an unsigned integer to prime numbers. it will work normally if I define the data type as "int", if I change it to "long", result will be wrong. I don't know why. BTW, I used Win-TC as my compiler. Code as below: #include "stdio.h" #define True 0xff #define False 0x00 char DividerIsPr...
