glob_match_len(9)

✨ NAME ✨

okay bestie, welcome to the Kernel API Manual 💖 — the main character here is glob_match_len(9), and it does exactly what it says on the tin: a glob match against a length-bounded string. no cap, that's the whole vibe check 🎀

🌸 SYNOPSIS 🌸

       bool __pure glob_match_len (char const *pat , char const *str , size_t
       len );

🎀 ARGUMENTS 🎀

• pat — the shell-style pattern you're matching against. slay 💅
• str — the string being matched. it literally need not be NUL-terminated 🫶
• len — how many bytes of str may be read. that's the boundary, bestie 🦋

🦋 DESCRIPTION 🦋

so it's like glob_match, except str is only read up to len bytes — which means it can be used on buffers that are not NUL-terminated (e.g. trace event fields). iconic use case, honestly 🔥

and yes: a NUL byte within len still terminates the string. important detail, don't sleep on it 💀

🌈 SEE ALSO 🌈

mwah 💋 this page's source/version footer is ./lib, it's dated October 2026, and it stars glob_match_len(9) — bye bestie, go read those bounded bytes 🫶✨
