tty_port_register_device(9)
Hey bestie! Welcome to the Kernel API Manual, where we're talking about tty_port_register_device(9) today. Buckle up, because this is gonna be iconic πβ¨
β¨ NAME β¨
tty_port_register_device β register tty device, and honestly it's giving main character energy ππ
. No cap, this is the function you call when you need to register a tty device.
πΈ SYNOPSIS πΈ
struct device * tty_port_register_device (struct tty_port *port , struct
tty_driver *driver , unsigned index , struct device *device );
π ARGUMENTS π
portβ thetty_portof the device. This is literally the port, bestie. It's the main character of this whole operation πβ¨driverβ thetty_driverfor this device. Like, the driver that drives this device, obviously ππ¨indexβ the index of the tty. It's the number that tells you which tty you're talking about. Periodt π’πdeviceβ the parent if it exists, otherwiseNULL. So if there's a parent device, you pass it here; if not, you passNULL. Simple as that πΈ
π DESCRIPTION π
Okay so here's the tea β: this function is literally the same as tty_register_device, except the port you provide gets linked to a concrete tty specified by index. That's the whole vibe, no cap.
Use this or tty_port_install (or both, go off π). And if you're thinking about calling tty_port_link_device, save it for a last resort β like, only if you absolutely have to, bestie.
Last resort alert! Call tty_port_link_device as a last resort. Don't come for me, I'm just the messenger π
