✨ make_vio_pool(9) ✨

okay so bestie, we're opening a page from the Kernel API Manual — the main character here is make_vio_pool(9), and it's literally here to create a new vio pool. no cap, let's get into it 💅

🌸 NAME 🌸

make_vio_pool — Create a new vio pool. 🦋

block_count , thread_id_t thread_id , enum vio_type vio_type , enum
vio_priority priority , void *context , struct vio_pool **pool_ptr );

🎀 ARGUMENTS 🎀
