multiprocessing.Queue.put(,,0) not documented

[Skaperen]

in the documentation for multiprocessing.Queue.put(), it describes what happens when block (2nd argument) is True (the default) and timeout (3rd argument) is None (the default) or a positive number. but it does not say what happens for a number value of zero. i'm hoping it raises the queue.Full exception immediately if the there is no available queue slot. or do i need to set block (2nd argument) to False?

i am reading this in the Library Reference PDF for version 3.7.4 even though i have 3.6.8.

If the documentation is weak in a particular area, I'd build my own test cases and see what is actually happening.
I'd probably also write up the documentation that should be there and submit that to python.org

It’s good to bear in mind that people develop Python language for annual salary of $0.

If one has interest and little spare time I suggest watching Raymond Hettinger Being a core developer in Python
