In main(), we declare a variable called thread_id, which is of type pthread_t, which is an integer used to identify the thread in the system. After declaring thread_id, we call pthread_create() function to create a thread. pthread_create() takes 4 arguments.
pthread_create() inspects this address space before creating a new thread. A realistic limit is 200 to 400 threads.
pthread_create simply creates a thread. Not "a kernel-level thread" or "a user-level thread".
the following two thread creation mechanisms are functionally equivalent: rc = pthread_create(&t, NULL, foo, NULL); rc = pthread_create(&t, &attr, foo, NULL); The cancellation state of the new thread is PTHREAD_CANCEL_ENABLE. The cancellation type of the new thread is PTHREAD_CANCEL_DEFERRED.
I'm making a c file for a dispatch queue that gets a task and put it in to a queue which is the linked list. In order to do this, I need to create threads using
pthread_t cThread; if(pthread_create(&cThread, NULL, work, param)){ perror("ERROR creating thread."); } However I need to make another function that goes into 'work' and 'param' variable as parameters of create function. My friend told me that I just need to put any code in the work function that loops infinitely so the thread does not die.. Can anyone explain each parameter goes in to the pthread_create function- especially for work and param? I searched Google for this, but most of tutorials are so hard to understand the concept...
