π¦ iio_backend_extend_chan_spec (9) β Kernel API Manual
okay so bestie, welcome to the group chat where we talk about the kernel API manual page for iio_backend_extend_chan_spec(9). yes the header is doing the thing where it abbreviates itself with ... β that's just the man page being dramatic, the real name is right below π
β¨ NAME β¨
iio_backend_extend_chan_spec β extend an IIO channel π
πΈ SYNOPSIS πΈ
int iio_backend_extend_chan_spec (struct iio_backend *back , struct
iio_chan_spec *chan );
π ARGUMENTS π
backβ the backend device, like, the one doing the extending π«Άchanβ the IIO channel, the main character getting extended β¨
π₯ DESCRIPTION π₯
so here's the vibe: some backends have their own little special functionalities, right? and because of that, they're literally capable of extending a frontend's channel. it's giving teamwork, it's giving "you grow, I grow" π no cap, that's the whole bit.
β RETURN β
0on success π- a negative error number on failure π (classic kernel behaviour, we respect it)
