IEEE1284_FREE_PORTS(3)

💖 IEEE1284_FREE_PORTS 💖

okay bestie, so this is the manual page for IEEE1284_FREE_PORTS(3) — it lives in section 3 (the functions girlies 🎀). And fr fr, it's about cleaning up your mess in the cutest, safest way possible. no cap.

✨ NAME ✨

ieee1284_free_ports — safely deallocate a port list 🧹💅

🦋 SYNOPSIS 🦋

#include <ieee1284.h>

void ieee1284_free_ports(struct parport_list *list);

🌸 DESCRIPTION 🌸

so like. when you're done with your port list — like, fully done, not just "i'll come back to it" done — your program should call ieee1284_free_ports and hand it a pointer to the parport_list structure. which structure? the one holding the list of ports that ieee1284_find_ports(3) gave you. that's the one. that's the girl. 🫶

and here's the part that's giving main character energy: the ports are reference counted ✨ — that's what ieee1284_open and ieee1284_close are doing with them. so the way that you can just free the port list even if it still contains pointers to ports that are still open?? iconic. truly. the list can go, the ports stay valid, nobody gets hurt. periodt. 💀🔥

no double-freeing, no dangling chaos, no drama. we love a graceful exit. 🎀
