Question

when you create thread using thread_create and pass the function, does the function goes forever if there is infinite loop in the function?
eg

for(;;){
    //dosomthing
}

Does the thread keep “do somthing” until the thread is destroyed or the program is finished?

Thanx

Answer 1

When you invoke thread_create() the thread that gets created will itself invoke the function you passed. So for example:

pthread_t thread1;
pthread_create(&thread1, NULL, thread_do, NULL);

will make a new thread and the new thread will run the function thread_do().
If now you have previously defined thread_do() as:

void* thread_do(){

  for(;;){
    // do something
  }

  return NULL;
}

then the thread will go to an endless loop indeed.
