EGD_SENSOR_TYPE(3)

💖 EGD_SENSOR_TYPE 💖

okay bestie, welcome to the EGD_SENSOR_TYPE(3) page from the EEGDEV library manual — yes it's a real manual page, yes it's a whole vibe, and yes we're gonna read it together 🫶

---

✨ NAME ✨

egd_sensor_type, egd_sensor_name — grab the id or the name of a sensor type, whichever way you're going 🎀

---

🌸 SYNOPSIS 🌸

#include <eegdev.h>

int egd_sensor_type(const char* sname);
const char* egd_sensor_name(int stype);

like, that's it. two little functions. iconic. 💅

---

🦋 DESCRIPTION 🦋

so egd_sensor_type() hands you back the identifier code of whatever sensor type is called sname. and egd_sensor_name() is literally the reverse glow-up: you give it the sensor type identified by stype, and it retrieves the name for you. it's giving mutuals. 🔁

now here's the tea, bestie: depending on which acquisition devices the library has actually accessed, the sensor type identifier for a given name may be different from a previous program execution. not a bug, just how it is, no cap. but once an association has been established, it is ensured that it will remain the same until the process termination. periodt. 💯

and additionally — this part is the iconique part — the sensor types named "eeg", "trigger" and "undefined" are always associated respectively to 0, 1 and 2. those three never switch up on you. main character energy. 👑

---

🌈 RETURN VALUE 🌈

• when it works out: egd_sensor_type() returns a non negative value, which is the identifier of the sensor type called name. and if it doesn't work out? it returns -1. 😭
• when it works out: egd_sensor_name() returns the name of the sensor type identified by stype. and if it doesn't work out? NULL is returned, and errno is set accordingly. rude but fair.

---

💀 ERRORS 💀

egd_sensor_type() or egd_sensor_name() will fail if:

• EINVAL — sname is NULL or refers to an unknown sensor type, or stype is not a known sensor type identifier. so like, don't pass garbage, bestie, they will clock it immediately 🙈
