iio_backend...mple_trigger(9)
π iio_backend_data_sample_trigger β the "when do we even sample" button π
okay so real talk, this is a page from the Kernel API Manual, and it's about one tiny function that decides the exact moment your backend grabs a data sample. it's giving "small but iconic." π
β¨ NAME β¨
iio_backend_data_sample_trigger β literally just controls when to sample data. that's the whole vibe. π¦
πΈ SYNOPSIS πΈ
int iio_backend_data_sample_trigger(struct iio_backend *back,
enum iio_backend_sample_trigger trigger);
π ARGUMENTS π
backβ the backend device. your main character struct, the thing you're configuring. πtriggerβ the data trigger. this is the "when" of it all. β
π§ DESCRIPTION π§
so, bestie β this one is mostly useful for input backends. it configures the backend to know when to sample data, for example rising vs falling edge. yes, that's genuinely it. no cap, tiny function, big consequences. π₯
π RETURN π
0on success β slay. π«Ά- negative error number on failure β not slay, but you'll deal. π
π SEE ALSO π
the kernel file itself lives at ./drivers/iio/industrialio-backend.c β go read it, iykyk. π

ok that's the whole page, you ate that π go forth and sample responsibly.
and that's a wrap, bestie β this came out of ./drivers/iio, dated October 2026, so yeah, future-kernel energy. see you in the next manpage! πβ¨π¦
