After <code>pthread_join()</code> Add <pre><code>/* Last thing that main() should do */ pthread_exit(NULL); </code></pre> For more details pls refer <a href="https://computing.llnl.gov/tutorials/pthreads/" rel="nofollow">here</a>. pthread_join() is used to make the main() thread wait till all the threads completes it's execution. Control reaches the pthread_join(), when that particular thread completes it's execution. So if you try to cancel/kill that particular thread, error will be returned. Sample Code <pre><code> #include <pthread.h> #include <stdio.h> #include <stdlib.h> #define NUM_THREADS 4 void *BusyWork(void *t) { int i; long tid; tid = (long)t; printf("Thread %ld starting...\n",tid); pthread_exit((void*) t); //Exits that current thread. } int main (int argc, char *argv[]) { pthread_t thread[NUM_THREADS]; int rc; long t; void *status; for(t=0; t<NUM_THREADS; t++) { printf("Main: creating thread %ld\n", t); rc = pthread_create(&thread[t], NULL, BusyWork, (void *)t); if (rc) { printf("ERROR; return code from pthread_create() is %d\n", rc); exit(-1); } } /* Wait for completion */ for(t=0; t<NUM_THREADS; t++) { rc = pthread_join(thread[t], &status); if (rc) { printf("ERROR; return code from pthread_join() is %d\n", rc); exit(-1); } printf("Main: completed join with thread %ld having a status of %ld\n",t,(long)status); } printf("Main: program completed. Exiting.\n"); pthread_exit(NULL); // Exits main thread. } </code></pre> For @Joachim Pileborg <pre><code>#include <pthread.h> #include <stdio.h> #include <stdlib.h> #define NUM_THREADS 4 void *BusyWork(void *t) { int i; long tid; tid = (long)t; printf("Thread %ld starting...\n",tid); for(i = 0; i <10000000; i++) printf("\n Thread: %ld, %d", tid, i); pthread_exit((void*) t); //Exits that current thread. } int main (int argc, char *argv[]) { pthread_t thread[NUM_THREADS]; int rc; long t; void *status; for(t=0; t<NUM_THREADS; t++) { printf("Main: creating thread %ld\n", t); rc = pthread_create(&thread[t], NULL, BusyWork, (void *)t); if (rc) { printf("ERROR; return code from pthread_create() is %d\n", rc); exit(-1); } } //printf("Main: program completed. Exiting.\n"); pthread_exit(NULL); // Exits main thread(work will be done). //return 0;//( Threads will exit once main exits.) } </code></pre>

1. POpthread_join function kill the thread after execution or we need to call pthread_cancel/pthread_exit?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
