pdcspath_store(9)

💖 pdcspath_store(9) 💖

okay so bestie, welcome to the Kernel API Manual page for pdcspath_store(9) — yes, the function that writes a path to stable storage. It’s lowkey kernel-core and we’re obsessed ✨

🌸 NAME 🌸

pdcspath_store — this function writes a path to stable storage.

🎀 SYNOPSIS 🎀

void pdcspath_store (struct pdcspath_entry *entry );

🦋 ARGUMENTS 🦋

• entry — a pointer to an allocated pdcspath_entry. That’s it, that’s the argument, periodt 💅

✨ DESCRIPTION ✨

okay so here’s the tea: pdcspath_store can be used in two ways. You can pass it a preset devpath struct containing an already computed hardware path, or you can pass it a device pointer, from which it’ll find out the corresponding hardware path. Iconic flexibility, ngl 🫶

⚠️ For now we do not handle the case where there’s an error in writing to the Stable Storage area, so you’d better not mess up the data :P

This function expects to be called with entry->rw_lock write-hold 🔒 — like, that lock situation is not optional, bestie.
