Sometimes a device needs to be open once again.
So what this means is not allow the second album before the release of the first movie.
So someone has already opened the device and now they're working on it and they have not closed door
in this case, not a second application to open the device if it goes in open
and filled out and I can destroy them and.
NBG.
So I think this be a busy.
So how can we implement this thing?
So this is needed to avoid any concurrency issues, like if your driver supports one Democrats, only
one that process can access, not one to have concurrent access.
You can use the scenario that you can avoid open access in an already in already an application using
retrievals if you have already an application using your device.
And some other application was already considered very, very busy.
So I can use Adamec variables.
I out make money with one.
The open function.
I think remote and check, I will remember this well and I will check with the values and the values.
This must be success.
If the value is not zero, if the value is negative, then I think the value of is.
In the release function, I think the value of anonymity.
So what I'm doing is our initial value of value, it was value is one in all the value in relation to
the world.
One.
And.
So let's call.
So I have this ironic when I'm initializing it one so I don't make it, we have to make that evidence.
Otherwise there maybe it is conditions if both are trying to access the same scene.
So using it will make sure that instructions will be executed without any security.
So it was only one first.
Discriminating and testing is zero if it is not zero.
I mean, getting it back and I'm going to need it if it is zero.
Then I'm coming out of the November.
So I make the best dance.
Zero.
If the value is.
So the result is zero and if one.
This has been one zero eight zero zero.
And in the release function, I mean, the open function and diclemente and taking the value is zero
and in the release function.
So the call.
Let's see that cool.
So, yeah, I'm having to take some first read through to one that creates a quality function, the
second protocol function, both of them call function.
So the both of them call or email message.
The device must open.
The device must have known the sleeper bicycle's that I call first.
No, which is not.
If it is successful, then goes first place again and it goes right and closes the final second.
Third continue to perform the same operation.
But it should be if it is Lisandro excessive to open the.
Selex, Campinas.
And beta test at see one trial successfully opening the mine, the second to open the file, because
all of the entries using the device known as the second, third and fourth in the device.
So this is one access control mechanism where they can allow only one application to access one device
and they can then I feel is if someone is already.
Using the device or some other application to access the device.
