Would this be anything other than "available externally" linkage? (either
this module is responsible for emitting the definition of this function for
other modules to call, or it's not - if it's not, either this module
depends on another module to provide a definition (this would be "available
externally") or it doesn't (this would be "internal" linkage")) - I
think... though I'm sort of jumping into the middle of some of this &
might've missed some context, sorry.
