💖 vmballoon_send_get_target(9) 💖

okay so bestie, we're in the Kernel API Manual, section 9 — this page is all about vmballoon_send_get_target, and it's giving "ask the host what balloon size it wants" energy ✨. no cap, it's a whole little kernel-API moment.

🌸 NAME 🌸

vmballoon_send_get_target — retrieve the desired balloon size from the host. literally the mission, and it ate 💅.

✨ SYNOPSIS ✨

int vmballoon_send_get_target (struct vmballoon *b );

🎀 ARGUMENTS 🎀

• b — a pointer to the balloon. bestie, that's the one and only argument 🫶.

💫 RETURN 💫

• Returns zero on success. slay.
• Returns EINVAL if the limit does not fit in 32-bit, as required by the host-guest protocol. not me being picky, the protocol said what it said 💅.
• Returns EIO if an error occurred in communicating with the host. communication breakdown, tragic 😭.
