I prefer bind.

Please provide a code sample that shows your problems. Also, make sure
you create the two threads first before you you call any join().

Since you are calling your thread function helloworld, I suspect
you're using the threads to print out some text on the console. Some
systems will provide a basic locking scheme when several threads
accessing stdout file. Use an endless loop in your thread function and
you'll see them running concurrently.
