💖 qcom_smem_get_free_space(9) 💖

okay so this is a page straight out of the Kernel API Manual, and honestly? it's a little cutie. we're talking about qcom_smem_get_free_space — say it with me, it's a mouthful but she's worth it 🫶

✨ NAME ✨

qcom_smem_get_free_space — retrieve amount of free space in a partition 💅

✨ SYNOPSIS ✨

int qcom_smem_get_free_space (unsigned int host );

✨ ARGUMENTS ✨

• host — the remote processor identifying a partition, or -1. yep, that's it, that's the whole argument, and she's carrying the entire vibe check of this function on her shoulders 😭

✨ DESCRIPTION ✨

so the tea is: this one's to be used by smem clients as a quick way to figure out whether any new allocations has been made. that's literally the whole point — a fast little peek, no cap. lowkey iconic that a function this small gets its own manpage 🎀

✨ RETURN ✨

• on success you get the number of available bytes ✨
• on failure you get a negative errno 💀 (so like, check it, bestie, don't just assume it worked)

✨ SEE ALSO ✨

the kernel file lives at ./drivers/soc/qcom/smem.c — go read her, she's long but she's the main character 👑
