How to use readvdd33()?

I want to use the readvdd33() function that's being called in the NodeMCU firmware, but I get an implicit declaration error on compile. I guess it can't find the definition.
I'm not familiar enough with this stuff to fix it. Can anyone help? I'm using the esphttpd example code in CHERTS' dev kit.

Figured out it has to do with the compile order. If I throw in a declaration before the function that calls it, it compiles.

Okay, so this works, but the question is...Is this the proper way to do it? Do I have to include declarations for all SDK system functions that I want to use?

Yes. That's the normal way of using external functions in C.
