 The \fBpthread_rwlock_rdlock()\fR function applies a read lock to the
 read-write lock referenced by \fIrwlock\fR.  The calling thread acquires the
 read lock if a writer does not hold the lock and there are no writers blocked
 on the lock.

 The \fBpthread_rwlock_tryrdlock()\fR function applies a read lock like the
 \fBpthread_rwlock_rdlock()\fR function, with the exception that the function
 fails if the equivalent \fBpthread_rwlock_rdlock()\fR call would have blocked
 the calling thread.  In no case will the \fBpthread_rwlock_tryrdlock()\fR
-function ever bloc. It always either acquires the lock or fails and returns
