💅 dso__data_write_cache_addr(9) 💅

okay so bestie, this page lives in the Kernel API Manual, and it’s giving “write into the dso data cache at a dso address” energy. Let’s get into it 🫶✨

🎀 NAME 🎀

dso__data_write_cache_addr — write data to dso data cache at dso address 💖

---

🌈 SYNOPSIS 🌈

ssize_t dso__data_write_cache_addr (struct dso *dso , struct map *map ,
       struct machine *machine , u64 addr , const u8 *data , ssize_t size );

🧾 ARGUMENTS 🧾

• dso — dso object 🦋
• map — -- undescribed -- 👀 the manpage literally says that, so no cap, I’m not inventing a whole personality for it
• machine — machine object ⭐
• addr — -- undescribed -- again bestie, that’s all it says 💀
• data — buffer to write 🌸
• size — size of the data buffer 🎀

---

✨ DESCRIPTION ✨

This is the external interface for writing into the dso file data cache. Big important part: it does not change the file itself. The file stays untouched — periodt 💅

⚠️ caveat bestie: this writes into the dso file data cache, but it does not change the file itself. Do not forget that part, fr fr.
