scoped_user_rw_access(9)

💖 NAME 💖

okay bestie, welcome to scoped_user_rw_access(9) from the Kernel API Manual — this one is literally about starting a scoped user read/write access. slay.

✨ SYNOPSIS ✨

scoped_user_rw_access (uptr , elbl );

🎀 ARGUMENTS 🎀

• uptr — pointer to the user space address to read from and write to. iconic little address, honestly.
• elbl — the error label to goto when the access region is rejected. it's giving emergency exit energy.

🦋 DESCRIPTION 🦋

so the size of the access starting from uptr is determined via sizeof(*uptr)). yes bestie, that's the whole vibe.

for further information, see __scoped_user_access above. iykyk.
