General / Pass data to a thread function

« on: October 02, 2010, 04:19:34 am »

Hi, I have a simple question about passing a variable to a thread function that I think it's easy to answer.

I was following this tutorial:
http://www.sfml-dev.org/tutorials/1.6/system-threads.php
And I read the part that explains my question, however I'm not having success when I try to pass a variable to the thread function.


I have the variable int n declared on the main, where n's value is 5.
Now I want to pass this value to a threaded function.
I tried the following:

Code: [Select]


void print_Console(void *UserData)
{
int* n = static_cast<int*>(UserData);
cout << "n=" << *n << endl;
}

int main()
{
int n=2; //EDITED AT Sat Oct 02, 2010 11:50 am
Thread th1(&print_Console, &n);
th1.Launch();
}


But it's not outputting n correctly.
So, what could be wrong here?

Thanks in advance

Audio / Failed to load sound buffer from file

« on: September 29, 2010, 08:26:38 pm »

Hi, I'm new to the forums so I'm not sure if I'm posting in the correct section, but here it goes.

I tried making a program in Visual Studio C++ 2008 using SFML, that would play a simple .wav file. However when I run it I only get the message:
"Failed to load sound buffer from file "sound.wav".

The code is the default one provided on the Audio tutorial:
http://www.sfml-dev.org/tutorials/1.6/audio-sound.php

source file in: http://www.sfml-dev.org/tutorials/1.6/sources/audio-sound.cpp

I've included libsndfile-1 and openal32 on the exe folder. The sound is present on the folder as well and is named sound.wav

What could be wrong?

Thanks in advance for any help
