I think this function could use a comment to indicate what it does.

Too much indentation for the second line there.

Maybe that declaration should be put in a common.h header file?

I think that should be bool to match the function return type.

Why 17? Seems like a magic number that should be a #define.

I think this array could be static const. const at least.

I think you could remove this assertion and just add a default switch
case below to catch invalid values.

The indentation here and below is a bit off.
