  .LP
  The \fBsem_timedwait()\fR function locks the semaphore referenced by \fIsem\fR
  as in the \fBsem_wait\fR(3C) function. However, if the semaphore cannot be
  locked without waiting for another process or thread to unlock the semaphore by
  performing a \fBsem_post\fR(3C) function, this wait is terminated when the

  Under no circumstance does the function fail with a timeout if the semaphore
  can be locked immediately. The validity of the \fIabs_timeout\fR need not be
  checked if the semaphore can be locked immediately.
  .SH RETURN VALUES
- .sp
  .LP
  The \fBsem_timedwait()\fR and \fBsem_reltimedwait_np()\fR functions return 0 if
  the calling process successfully performed the semaphore lock operation on the
  semaphore designated by \fIsem\fR. If the call was unsuccessful, the state of
  the semaphore is be unchanged and the function returns -1 and sets \fBerrno\fR
  to indicate the error.
