DLL - Pointer to Boolean

[Edmi]

Actually, I did something wrong on the first try, but the idea with the array solved the problem.

Thank you so much for the help everyone.

But given that I am only using one channel, the pointers "mprValChan1-3" should be passed as NULL. That is the first question, is it possible to pass a null pointer in LabView?

In case you need it in the future, the correct way to pass a NULL pointer to a function from LabVIEW is to configure that parameter as a pointer-sized integer, passed BY VALUE, and wire 0 to it.

Thank you nathand, I'll remember that. Probably I'll use that in this program.
