Thread::Queue(3p)Perl Programmers Reference GuidThread::Queue(3p)

NAME
     Thread::Queue - thread-safe queues

SYNOPSIS
	 use Thread::Queue;
	 my $q = new Thread::Queue;
	 $q->enqueue("foo", "bar");
	 my $foo = $q->dequeue;	   # The "bar" is still in the queue.
	 my $foo = $q->dequeue_nb; # returns "bar", or undef if the queue was empty
	 my $left = $q->pending;   # returns the number of items still in the queue

DESCRIPTION
     A queue, as implemented by "Thread::Queue" is a thread-safe
     data structure much like a list.  Any number of threads can
     safely add elements to the end of the list, or remove ele-
     ments from the head of the list. (Queues don't permit adding
     or removing elements from the middle of the list).

FUNCTIONS AND METHODS
     new     The "new" function creates a new empty queue.

     enqueue LIST
	     The "enqueue" method adds a list of scalars on to
	     the end of the queue. The queue will grow as needed
	     to accommodate the list.

     dequeue The "dequeue" method removes a scalar from the head
	     of the queue and returns it. If the queue is
	     currently empty, "dequeue" will block the thread
	     until another thread "enqueue"s a scalar.

     dequeue_nb
	     The "dequeue_nb" method, like the "dequeue" method,
	     removes a scalar from the head of the queue and
	     returns it. Unlike "dequeue", though, "dequeue_nb"
	     won't block if the queue is empty, instead returning
	     "undef".

     pending The "pending" method returns the number of items
	     still in the queue.
