iio_device_attach_buffer(9)

📦 version 7.3.1, in nixpkgs unstable

💖 iio_device_attach_buffer 💖

okay so bestie, welcome to the iio_device_attach_buffer(9) page from the Kernel API Manual — yes, that's the kernel API manual, we're in the big leagues now 🎀

NAME

iio_device_attach_buffer — attach a buffer to a IIO device. that's it, that's the whole vibe ✨

🌸 SYNOPSIS 🌸

int iio_device_attach_buffer (struct iio_dev *indio_dev , struct iio_buffer *buffer );

literally the whole function signature, no notes, copy it exactly, periodt 💅

🦋 ARGUMENTS 🦋

  • indio_dev — the device the buffer should be attached to. like, this is the main character device in question 👑
  • buffer — the buffer to attach to the device. this one's the plus-one being brought to the party 🫶

✨ DESCRIPTION ✨

okay so the actual tea ☕: this function attaches a buffer to a IIO device, and it returns 0 if successful, negative if error. simple as that, no cap.

the buffer stays attached to the device until the device is freed. like, it's committed, it's not going anywhere until the device itself is done 💀

for legacy reasons — and yeah, we love a legacy reason 🙈 — the first attached buffer will also be assigned to indio_dev->buffer. so the first one gets that extra special spot, iykyk.

and the array allocated here? it will be freed via the iio_device_detach_buffers call, which is handled by the iio_device_free. so like, cleanup is already taken care of, you don't have to worry about it, the kernel's got you bestie 💜
