✨ __devm_iio_trigger_alloc(9) ✨

okay bestie, welcome to the Kernel API Manual 💅 this one's a little function with a big name and honestly it's giving "resource management but make it effortless". Let's get into it 🫶

🌸 NAME 🌸

__devm_iio_trigger_alloc — it's the resource-managed version of iio_trigger_alloc(), aka Managed iio_trigger_alloc. The whole vibe? Any iio_trigger you allocate with this function gets automatically freed on driver detach ✨ like, you don't have to remember to clean up. she handles it. iconic behaviour fr fr 👑

🦋 SYNOPSIS 🦋

struct iio_trigger * __devm_iio_trigger_alloc (struct device *parent ,
   struct module *this_mod , const char *fmt , ... );

🎀 ARGUMENTS 🎀

  • parent — the device you're allocating the iio_trigger for 🧚
  • this_mod — the module that's doing the allocating, bestie
  • fmt — the trigger name format. and listen, if it's got format specifiers in it, the extra arguments that come after fmt get formatted and dropped into the resulting string, replacing their respective specifiers 💖 it's literally printf energy
  • ... — variable arguments, the lil extras 🌈

⭐ RETURN ⭐

On success you get a pointer to the allocated iio_trigger 💫 on failure? NULL. that's it, that's the whole story 😭

ngl the "automatically freed on driver detach" part is the whole main character moment here — no manual cleanup arc, no leaked memory plot twist 💀
