💖 LLAPI_LOV_STRING_PATTERN(3) 💖

okay bestie, so this is a page from section 3 of the Lustre Library Functions manual — the part where we hang out with the user-level library calls. And this one? It's the lil translator that takes a cute human-readable pattern name and turns it into a mask. iconic behavior, honestly. ✨

🌸 NAME 🌸

llapi_lov_string_pattern — convert a pattern name string into a LOV_PATTERN mask, no cap

🦋 SYNOPSIS 🦋

#include <lustre/lustreapi.h>

int llapi_lov_string_pattern(const char *string, enum lov_pattern *pattern);

✨ DESCRIPTION ✨

so llapi_lov_string_pattern() is the one doing the translating 💅 it takes string, which is a comma-separated list of LOV pattern names, and it converts that whole lil list into a mask of LOV_PATTERN_* flags — which it hands back to you in pattern.

like, you give it the names, it gives you the mask. that's the whole vibe. 🫶

🎀 RETURN VALUES 🎀

  • it returns 0 when it's slaying — aka on success 👑
  • on failure it returns -EINVAL, and in that case errno gets set appropriately, so go check it
no shame in a fail, bestie, just read the errno bestie 😭

🌈 AVAILABILITY 🌈

llapi_lov_string_pattern() has been part of the lustre(7) user application interface library since release 2.17.0 — so if your Lustre is older than that, she's not here yet 🙈
