#include "Thread.h"

void * Thread::dispatch(void * ptr)
{
    if (!ptr)
       return 0;

    static_cast<Thread *>(ptr)->run();
    pthread_exit(ptr);

void Thread::start()
{
    pthread_create(&thread, 0, Thread::dispatch, this);

void Thread::join()
{
    pthread_join(thread, (void **) 0);
}

This is an ABC, as you can see the derived class must implement a
run() function... When you derived from this, you will call the
start() method wich will create the pthread.. .the creation will
callback the start() function which will execute the derived classes
run(). after run() finishes, pthread_exit() will be called to clean up
the memory.
