Details
If the data queue is empty, the function waits up to the
timeout
value.
If data is not available in the data queue before the
timeout
expires, the return value is
nil
.
The entries in the data queue are removed in first-in, first-out (FIFO) order.
If the value is a table, a duplicate of the original table and any subtables is made. The duplicate table
does not contain any references to the original table or to any subtables.
Example
dataqueue.clear()
for i = 1, 10 do
dataqueue.add(i)
end
print("There are " .. dataqueue.count
.. " items in the data queue")
while dataqueue.count > 0 do
x = dataqueue.next()
print(x)
end
print("There are " .. dataqueue.count
.. " items in the data queue")
Clears the data queue, adds ten entries, then
reads the entries from the data queue. Note that
your output may differ depending on the setting
of
