What is this code doing exactly? Please explain in detail so I can better understand the process. Thank you #include #include #include #include #include #define MAX 100 static void * threadFunc (void *arg) { char *str = (char *) arg; int count = 0; printf("\nThread: threadFunc started \n"); while(1) { sleep(1); printf("\n threadFunc: executing loop \n"); } sleep(5); printf("\nThread: threadFunc exiting \n"); } int main(int argc, char *argv[]) // init thread or main thread { pthread_t t1_id; void *res; int s; int count; s = pthread_create(&t1_id, NULL, threadFunc, NULL); if ( s != 0 ) //if creating the new thread is successful, then s will be zero. { perror("Thread create error"); } for (count = 0; count < 10; count++) { sleep(2); printf("\n main thread: count value = (%d) \n", count); } pthread_cancel(t1_id); printf("main thread: exiting now \n "); pthread_exit(NULL); //The main will exit without waiting for the thread.
