Perhaps I'm assuming your syntax is literal C code when that is not  
what you meant?

The code you wrote explicitly defines a _static_ (i.e. private) symbol  
for storage that only the one compiled source file will be able to see  
the referenced storage, and only within the scope of the definition.

But I think Andreas Raab hit the nail on the head with his suggested  
ioLoadFunctionFrom() idea.
