Trouble with threads
« on: March 21, 2011, 09:38:50 pm »
HAI!

I am creating a file manager for Linux. I need to run iNotify while my app is running..
When it runs, it either runs my app, or inotify. but it cant run both. here is my code...

Code: [Select]


...

void inotify_check (void*) {

  ...

}

...

int main () {

  ...

  sf::Thread Thread(&inotify_check);

  while (running) {

    ...

    Thread.Launch();

    ...

  }

  ...

}


When I do this.. the thread runs, but it won't proccess the main part of the app.

I also tried this...

Code: [Select]


...

void inotify_check (void*) {

  ...

}

...

int main () {

  ...

  sf::Thread Thread(&inotify_check);

  while (running) {

    ...

    Thread.Launch();

    ...

    Thread.Terminate();

  }

  ...

}


But this keeps returning the error "Failed to create thread"

KTHXBYE!

We need to see more code. What would be great is a minimal and complete example that reproduces the problem.

Ok i got one thing working.. it runs the thread.. but it only runs it once.

e.g.

Code: [Select]

#include <SFML/System.hpp>
#include <iostream>
using namespace std;

bool running = true;

void MyThreadFunc(void* UserData) {

  cout << "hai";

}

int main () {

  sf::Thread Thread1(&MyThreadFunc);
  Thread1.Launch();

  while (running) {

    cout << "Welcome!";

  }

}


EDIT:

I got this working... but I am trying to do this with iNotify THEN it jams... should i post my code?

EDIT 2:

iNotify has to be constantly running and looking for events while my app is running

It's several hundred lines of code... I'll just try to explain what I need to do

I need to run my program, but while my program is running, I need to run iNotify constantly (checks system events)
