\section{The \code{critical} Construct}
|
|
\label{sec:critical}
|
|
|
|
The following example includes several \code{critical} constructs. The example
|
|
illustrates a queuing model in which a task is dequeued and worked on. To guard
|
|
against multiple threads dequeuing the same task, the dequeuing operation must
|
|
be in a \code{critical} region. Because the two queues in this example are independent,
|
|
they are protected by \code{critical} constructs with different names, \plc{xaxis}
|
|
and \plc{yaxis}.

The following example extends the previous example by adding the \code{hint} clause to the \code{critical} constructs.
