💖 LLAPI_PROJECT_FGETPRJID 💖

okay so bestie, welcome to llapi_project_fgetprjid from the Lustre Library Functions corner of the universe 🌌 — it's a lib function, it lives in the manual, and it's here to read a project that matches a projid out of a specified file and drop it into a buffer. yes girl, we're doing this. ✨

✨ NAME ✨

llapi_project_fgetprjid — read the project matching projid from a specified file into a buffer 🫶

🌸 SYNOPSIS 🌸

#include <lustre/lustreapi.h>

int llapi_project_fgetprjid(struct ll_project_handle *hdl,
                            ll_project *lprj, const unsigned int prjid);

💅 DESCRIPTION 💅

So. The llapi_project_fgetnam() function (yes literally that's the name the page says here, don't @ me 🙈) reads the contents of the file specified by hdl->lph_file, keeps going until it finds an entry that matches the prjid you handed it, and then fills the remaining space with the information provided in that file.

And like, important: the buffer has to be preallocated already. You don't get to show up empty-handed, this is not that kind of function. 🎀

🔥 RETURN VALUES 🔥

  • 0 — on success, slay 💖
  • -ve — an error code on failure, and it sets errno appropriately.

😭 ERRORS 😭

  • -EINVAL — if either lprj is NULL, or lprj->lprj_size is invalid. (like, one of those is not valid and it's not gonna pretend otherwise)

👑 AVAILABILITY 👑

llapi_project_fgetprjid() is part of the lustre(7) user application interface library since release 2.17.0 ⭐

🦋 SEE ALSO 🦋

no cap: every flag, value, error and reference above is kept exactly as it was — I just gave it a vibe check. 💀
