Using a class function in int main()

Question

I am having problems calling my functions from my main program.
These functions HAVE to be in my class.
How do I access them from my int main()?

#inc         


        

Answer 1

The two threads you create (via reader_writer()) do nothing. main() just goes into the first do loop with no way of getting out.

Also, you seem to have confused mutex, semaphores, and condition variables. The function names makes it look like you're trying to implement condition variables in your class. But you're building it as just wrappers to mutex locks.

And finally, you are calling pthread_mutex_lock() et al. on a pthread_t when those functions are supposed to be called on a pthread_mutex_t.

There probably are other errors, but these are the ones that really jump out. Basically, you need to review multi-threaded programming, both in terms of how threads are created, and how they are synchronized.
