cppi5_hdesc_get_pktlen(9)

✨ NAME ✨

okay so this is the cppi5_hdesc_get_pktlen(9) page in the Kernel API Manual, and it's literally about one tiny iconic job: cppi5_hdesc_get_pktlen — get Packet Length from HDesc. That's the whole vibe, bestie. 🎀

🦋 SYNOPSIS 🦋

u32 cppi5_hdesc_get_pktlen (struct cppi5_host_desc_t *desc );

It's giving "take a descriptor pointer, hand back a u32," no cap. ✨

🌸 ARGUMENTS 🌸

• desc — Host packet descriptor. That's the descriptor you're asking for the packet length from, periodt. 💅

💖 RETURN 💖

It returns the Packet Length from Host Packet Descriptor — literally the packet length, straight from the host packet descriptor. The way that it just gives you exactly that? Obsessed. 🫶
