a function declaration without a prototype is deprecated in all versions of C

### Problem:

We cannot compile the SDK on modern versions of clang, this will become a problem on gcc as well eventually. This has been obsolete since 1989 according to a post on [Stack Overflow](https://stackoverflow.com/questions/75943541/a-function-declaration-without-a-prototype-is-deprecated-in-all-versions-of-c)

### Solution:

Update the SDK so the methods in error.h have void in the prototype.

### Out of scope:

Is there anything the solution will intentionally NOT address? No

Start in error.h and review the SDK method declarations that lack a prototype. Update those declarations to include void, then compile the SDK with modern clang to verify the deprecation errors are resolved.
