When the main thread exits, all active threads are immediately
terminated. Since your main subroutine has nothing after the
pthread_create(), it immediately exits, thus your secondary thread has no
chance to run.
Add a delay at the end of the main thread to give the pthread_create() the
time it needs, or just pthread_join() to wait until the secondary thread
terminates.
