💫 NAME 💫

comedi_get_gate_source — get the gate for a subdevice, no big deal, just grabbing a gate 🎀

---

🌸 SYNOPSIS 🌸

#include <comedilib.h>

int comedi_get_gate_source(comedi_t * device, unsigned int subdevice,
                           unsigned int channel,
                           unsigned int gate_index,
                           unsigned int * gate_source);

alpha — yeah bestie, she's in her alpha era, still cooking, be nice to her 🙈

👑 DESCRIPTION 👑

so like, this function queries the gate for a subdevice, the way it was set up by comedi_set_gate_source. basically it's the "hey what's your gate rn" call. the currently configured gate source gets written into *gate_source — like, it goes in there, that's its home now 🏠

the possible values and their corresponding gates are driver-dependant, which means it's giving "ask your driver, not me" energy, iykyk. and here's the tea: if the subdevice does not support configuring its gates on a per-channel basis, then the channel parameter will be ignored. like, just straight up not reading it. ghosted. 💀

also, and this is important — this function is only useable on subdevices that provide support for the INSN_CONFIG_GET_GATE_SRC configuration instruction. if your subdevice doesn't speak that instruction, this whole thing is not it, periodt.

⭐ RETURN VALUE ⭐

• 0 on success — slay, we ate 💅
• -1 on error — not slay, something went wrong 😭
