  66      -.sp
  67   66  .LP
  68   67  The \fBpthread_rwlock_rdlock()\fR function applies a read lock to the
  69   68  read-write lock referenced by \fIrwlock\fR.  The calling thread acquires the
  70   69  read lock if a writer does not hold the lock and there are no writers blocked
  71   70  on the lock.
  72   71  .sp
  73   72  .LP
  74   73  The calling thread does not acquire the lock if a writer holds the lock or if
  75   74  writers of higher or equal priority are blocked on the lock; otherwise, the
  76   75  calling thread acquires the lock. If the read lock is not acquired, the calling
↓ open down ↓ 9 lines elided ↑ open up ↑ 
  86   85  The maximum number of concurrent read locks that a thread can hold on one
  87   86  read-write lock is currently set at 100,000, though this number could change in
  88   87  a future release. There is no imposed limit on the number of different threads
  89   88  that can apply a read lock to one read-write lock.
  90   89  .sp

  92   91  The \fBpthread_rwlock_tryrdlock()\fR function applies a read lock like the
  93   92  \fBpthread_rwlock_rdlock()\fR function, with the exception that the function
  94   93  fails if the equivalent \fBpthread_rwlock_rdlock()\fR call would have blocked
  95   94  the calling thread.  In no case will the \fBpthread_rwlock_tryrdlock()\fR
  96      -function ever bloc. It always either acquires the lock or fails and returns
       95 +function ever block. It always either acquires the lock or fails and returns
  97   96  immediately.
  98   97  .sp
  99   98  .LP
 100   99  Results are undefined if any of these functions are called with an
 101  100  uninitialized read-write lock.
 102  101  .sp
 103  102  .LP
 104  103  If a signal is delivered to a thread waiting for a read-write lock for reading,
 105  104  upon return from the signal handler the thread resumes waiting for the
 106  105  read-write lock for reading as if it was not interrupted.
 107  106  .SH RETURN VALUES
 108      -.sp
 109  107  .LP
 110  108  If successful, the \fBpthread_rwlock_rdlock()\fR function returns \fB0\fR.
 111  109  Otherwise, an error number is returned to indicate the error.
 112  110  .sp
 113  111  .LP
 114  112  The \fBpthread_rwlock_tryrdlock()\fR function returns \fB0\fR if the lock for
 115  113  reading on the read-write lock object referenced by \fIrwlock\fR is acquired.
 116  114  Otherwise an error number  is returned to indicate the error.

 120  117  The \fBpthread_rwlock_rdlock()\fR and \fBpthread_rwlock_tryrdlock()\fR
