tty_port_destroy(9)

tty_port_destroy(9) 💅

okay bestie, welcome to the Kernel API Manual — today’s main character is tty_port_destroy, and it’s literally the cleanup era we all need. ✨

🌸 NAME 🌸

tty_port_destroy — destroy inited port 🎀

✨ SYNOPSIS ✨

void tty_port_destroy (struct tty_port *port );

🎀 ARGUMENTS 🎀

• port — the tty port to be destroyed. yep, that’s the one getting its goodbye moment, bestie 💀

💖 DESCRIPTION 💖

so here’s the tea: when a port was initialized using tty_port_init, one has to destroy the port by this function. no cap, that’s the rule. 🫶

you can do it either indirectly by using tty_port refcounting (tty_port_put) or directly if refcounting is not used. pick your lane, but the port still needs its destroy moment. periodt. 💅
