💅 DESCRIPTION 💅

So here's the tea: this function is part of the Performance Co-Pilot Log Import API (go check LOGIMPORT(3) if you wanna see the whole vibe, iykyk), and pmiSetHostname sets the source hostname in the current context to be value. That's it. That's the whole job. Iconic, honestly.

And if you just... never call pmiSetHostname? Not me forgetting 🙈 — then the source hostname lowkey defaults to the hostname of the localhost. No cap, it just does that on its own. 🏠✨

---

😭 DIAGNOSTICS 😭

pmiSetHostname returns zero on success, else a negative value — and bestie, you can turn that negative value into an actual error message by calling pmiErrStr(3). Don't just stare at the negative number, go get the lore. 💀
