✨ seccomp_cache_check_allow(9) ✨

okay bestie, welcome to the Kernel API Manual page for seccomp_cache_check_allow — section 9, kernel API vibes only, this is the one 🫶

---

💅 NAME

seccomp_cache_check_allow — lookup seccomp cache 🔍✨

like, it literally goes and checks the cache, no cap

---

🎀 SYNOPSIS

bool seccomp_cache_check_allow (const struct seccomp_filter *sfilter ,
const struct seccomp_data *sd );

yes the parameters really are named sfilter and sd, we love a naming convention that ate 💅

---

🦋 ARGUMENTS

• sfilter — the seccomp filter 🌸 like, the filter itself, the main character
• sd — the seccomp data you're looking up the cache with 🔎 gotta feed it the right data or the lookup is giving nothing

---

💖 DESCRIPTION

Returns true if the seccomp_data is cached and allowed. periodt. ✨

that's it, that's the whole thing — both conditions though, ok? it has to be cached and allowed for you to get that true. not me being explicit about the and but someone had to say it 😭
