iio_hw_consumer_alloc(9)

💅 iio_hw_consumer_alloc(9) 💅

okay so this is a page from the Kernel API Manual, bestie — welcome to the IIO corner of the kernel, we're getting you a hardware consumer and it's gonna be cute 🎀

✨ NAME ✨

iio_hw_consumer_alloc — Allocate IIO hardware consumer

like, that's the whole job. it allocates the thing. that's it. that's the girlboss moment 🫶

🌸 SYNOPSIS 🌸

struct iio_hw_consumer * iio_hw_consumer_alloc (struct device *dev );

literally one argument, one return, no drama 💅 (and yeah, keep the spacing exactly like that, no cap)

🦋 ARGUMENTS 🦋

• dev — Pointer to consumer device. that's your device, the one doing the consuming. main character energy, honestly 👑

⭐ DESCRIPTION ⭐

okay so real talk: this returns a valid iio_hw_consumer on success, or a ERR_PTR on failure. that's the whole vibe check 🔥

⚠️ heads up bestie — the failure path is ERR_PTR, not NULL. so pls don't go doing a plain null check on this, use the proper error-pointer checks, iykyk 😭🙈
