✨ nfc_allocate_device ✨

Okay so bestie, welcome to the Kernel API Manual πŸ’– β€” this is the page for nfc_allocate_device(9), and honestly it's giving "birth of an NFC device" energy. Let's get into it πŸŽ€


🌸 NAME 🌸

nfc_allocate_device β€” allocate a new nfc device πŸ¦‹

Like, you're literally bringing a whole new NFC device into existence. Main character energy fr fr πŸ‘‘


✨ SYNOPSIS ✨

struct nfc_dev * nfc_allocate_device (const struct nfc_ops *ops , u32
supported_protocols , int tx_headroom , int tx_tailroom );

That's the whole signature, no cap. Four arguments, one struct nfc_dev * coming back at you πŸ’…


πŸ’œ ARGUMENTS πŸ’œ

  • ops β€” device operations. It's the const struct nfc_ops * β€” all the behaviour your device is gonna have πŸ’«
  • supported_protocols β€” NFC protocols supported by the device. A u32 bitmask situation, iykyk πŸ”₯
  • tx_headroom β€” reserved space at beginning of skb 🌸
  • tx_tailroom β€” reserved space at end of skb πŸ¦‹

Headroom at the front, tailroom at the back, and the payload living its best life in the middle. Periodt ✨
