The number of pollmsg structures and the number of pollfd structures in the arrays are specified by nmsgsfds. The poll() function identifies those file descriptors on which an application can read or write data, or on which an error event has occurred. listptr A pointer to an array of...
q = parallel.pool.PollableDataQueue; The helper function magicWithSend defined at the end of this example sends the sum of a magic square to a DataQueue or PollableDataQueue object, then returns that magic square. Use parfeval and backgroundPool to run the function magicWithSend in the ba...

poll notes this operation and returns the value to the client function. Then the time taken since parfeval was called is displayed. Note a delay of 3 s while the worker is computing something (in this case a long pause). Input Arguments collapse all pollablequeue— Pollable data queue ...

Retrieves and removes the head of the queue represented by this deque (in other words, the first element of this deque), waiting up to the specified wait time if necessary for an element to become available. This method is equivalent to #pollFirst(long,TimeUnit) pollFirst. Java documentatio...
