LLAPI_PCC_CLEAR(3)

💖 LLAPI_PCC_CLEAR(3) 💖

okay bestie, come sit with me, we're reading a Lustre Library Functions page together and honestly? it's a short one, we love that for us 🎀

✨ NAME ✨

llapi_pcc_clear — the function that removes every single PCC backend from a client. all of them. the whole roster. gone 💅

---

🦋 SYNOPSIS 🦋

#include <lustre/lustreapi.h>

int llapi_pcc_clear(const char *mntpath,
                    enum lu_pcc_cleanup_flags flags);

---

🌸 DESCRIPTION 🌸

so llapi_pcc_clear() deletes all PCC backends on the client whose mount point is referenced by mntpath. every one of them. it's giving spring cleaning, it's giving "clear the cache but make it permanent" ✨

and about that flags parameter? don't overthink it, bestie — for the usage of the input parameter flags, go look at llapi_pcc_del(). that's the main character for flag semantics, this one just borrows the vibe. iykyk 🫶
