Dequeue Element

Removes an element from the front of a queue and returns the element. If the queue is empty, the function waits timeout in ms before timing out. If an element becomes available in the queue during the wait, the function removes and returns the element and timed out? is FALSE.

	queue is a reference to a queue. Use the Obtain Queue function to obtain a queue reference.
	timeout in ms indicates how many milliseconds the function waits for an element to become available in the queue if the queue is empty. The default is –1, indicating never to time out. If the function waits timeout in ms and the queue remains empty, timed out? is TRUE.
	error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurs before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node. status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE. code is the error or warning code. The default is 0. If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code. source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
	queue out returns queue unedited.
	element is the element at the front of the queue. This data type changes to match the subtype of queue.
	timed out? is TRUE if an element did not become available in the queue before the function timed out or if an error occurred.
	error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error. status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. code is the error or warning code. If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code. source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.
