💖 EGD_CLOSE(3) — EEGDEV library manual 💖

okay bestie, welcome to the EEGDEV library manual, page EGD_CLOSE(3) ✨ this one's short and sweet and it's literally about saying bye to a device. no cap.

✨ NAME ✨

egd_close — close a device 🫶

🌸 SYNOPSIS 🌸

#include <eegdev.h>

int egd_close(struct eegdev* dev);

🎀 DESCRIPTION 🎀

so, egd_close() does the full send-off, bestie. it frees all the resources associated to the device referenced by dev and closes it. like, everything. gone. clean.

and the way that it also implicitly stops any running acquisition? iconic. you don't even have to ask, it just does it. 💅

🚨 okay this part matters, fr fr: after a successful call to egd_close(), the reference dev cannot be used any longer. it's done. it's over. don't touch it. don't call anything on it. it's giving "ghosted" and you need to respect that. 💀

👑 RETURN VALUE 👑

  • returns 0 in case of success 🎉
  • otherwise, -1 is returned and errno is set accordingly 😭

🌈 ERRORS 🌈

egd_close() will fail if:

  • EINVAL — dev is NULL. yeah. you passed nothing. there's no device to close, bestie 🙈

mood: closing a device is self-care. free the resources, stop the acquisition, log off, hydrate. 🦋
