💖 security_policycap_supported — the Kernel API Manual, but make it cute 💖

okay so bestie, welcome to the <pink>Kernel API Manual</pink> ✨ this one's a lil function called security_policycap_supported and honestly? it's giving "does the policy support this or not" energy. that's literally the whole vibe. let's get into it 🎀

🌸 NAME 🌸

security_policycap_supported — check for a specific policy capability 👑

like, you hand it a capability, it tells you if the currently loaded policy is down with it. simple. iconic. no cap.

✨ SYNOPSIS ✨

int security_policycap_supported (unsigned int req_cap );

yup, that's the whole signature. it returns an int, and it takes one unsigned int called req_cap. that's it. that's the function 🫶

🦋 ARGUMENTS 🦋

  • req_cap — the capability, bestie 💅 this is the specific policy capability you're asking about. it's an unsigned int. that's the whole argument. one job.

💜 DESCRIPTION 💜

okay so here's the tea ☕ — this function queries the currently loaded policy to see if it supports the capability you specified in req_cap.

and the answer comes back as:

  • true (1) — if the capability is supported 🔥 slay
  • false (0) — if it isn't supported 💀

that's the entire deal. it's a vibe check for policy capabilities. iykyk 🌈
