fwcaps32_to_caps16(9)

💖 NAME 💖

okay so this is the Kernel API Manual page for fwcaps32_to_caps16(9) — it's literally here to convert 32-bit Port Capabilities to 16-bits ✨

---

🎀 SYNOPSIS 🎀

fw_port_cap16_t fwcaps32_to_caps16 (fw_port_cap32_t caps32 );

You hand it a fw_port_cap32_t caps32, and it gives you back a fw_port_cap16_t. Cute little type glow-up 💅

---

🌸 ARGUMENTS 🌸

• caps32 — a 32-bit Port Capabilities value. That's the whole input, bestie 🫶

---

🦋 DESCRIPTION 🦋

It returns the equivalent 16-bit Port Capabilities value.

Lowkey important though: not all 32-bit Port Capabilities can be represented in the 16-bit Port Capabilities, and some fields/values may not make it. So yeah — not everything survives the downsize, no cap 😭💀
