USING IN (Critical section)
The instruction USE ... IN instruction automatically performs initialization and termination operations on critical sections. This statement makes it possible to "forget" these operations (mainly ending operations) and to make the code more readable for highlighting the block to which the functionality relates. Note: If the USE ... IN INSTRUCTION instruction via a RETURN instruction, the section is automatically ended.
Section is CriticalSection
Use Section IN
END
// Use of a named critical section
USING CriticalSection("MySection") IN
// Two threads will not be able to run this code at the same time
...
END
// Critical section on a variable
t is array <critical section> of int
USING CriticalSection(t) IN
// Operations on the array by one only thread at a time
...
END
