Okay bestie, welcome to the Kernel API Manual page for struct seccomp_notif_addfd(9) — manual name folded in right here, just like requested. The original NAME line has the dash with literally nothing after it, so we are not inventing a summary. Periodt. 💖

🧚 Members 🧚

This struct has a whole little cast, and every single one is important — no skipping, bestie:

• id — the ID of the seccomp notification. That's the notification's identity, iykyk. 🪪
• flags — SECCOMP_ADDFD_FLAG_*. Yep, that's the flag family exactly as written. 🚩
• srcfd — the local fd number. 💻
• newfd — optional remote FD number if the SETFD option is set, otherwise 0. 🔢
• newfd_flags — the O_* flags the remote FD should have applied. 🌈
