XDF_GET_CHANNEL(3)

💖 XDF_GET_CHANNEL(3) 💖

okay bestie, welcome to the xdffileio library manual — this one's a lil cutie, it's just gonna hand you a channel descriptor and that's it. no drama, no cap. ✨

🌸 NAME 🌸

xdf_get_channel — grab the channel descriptor handle for a specific index, bestie. that's the whole job. 💅

🎀 SYNOPSIS 🎀

#include <xdfio.h>

struct xdfch* xdf_get_channel(const struct xdf* xdf,
                              unsigned int index);

like. look at her. two args, one struct pointer back. she's serving simplicity. 🦋

✨ DESCRIPTION ✨

okay so xdf_get_channel() gets the channel descriptor of the channel that's stored at index index, inside the XDF file that the handle xdf is referencing.

that's it. that's the function. she's not complicated, she's just useful. 🫶

💜 RETURN VALUE 💜

xdf_get_channel() returns the handle to the requested channel descriptor when everything goes right — and NULL when it doesn't. so like, if you get NULL, that's your sign, that's the vibe check failing. 😭

🔥 ERRORS 🔥

• EINVAL — this one pops up when xdf is NULL, or when index is bigger than the number of channels. so either you're pointing at nothing, or you're reaching for a channel that does not exist. respectfully, stop that. 💀

👑 SEE ALSO 👑

• xdf_add_channel(3) — the one that puts channels in, so you can come back here and get them out. iconic duo fr fr. 🌈

mwah 💋 that's the page! this lil slice of the xdffileio library manual came to you from EPFL, dated 2010, and it's filed under XDF_GET_CHANNEL(3). go forth and fetch your channels, bestie — you got this. 💖✨🎀
