💜 DESCRIPTION 💜

so the pmem2_vm_reservation_get_size() function reads the size of the virtual memory reservation that was already created. it doesn't make one, it doesn't touch one, it just looks at it and tells you how big it is. a little nosy, a little iconic. 👑

the rsv parameter points to the structure describing the virtual memory reservation — and important detail bestie: that reservation has to have been created using the pmem2_vm_reservation_new(3) function. so like, you can't just hand it vibes. it needs an actual reservation. 🙈

🌈 RETURN VALUE 🌈

the pmem2_vm_reservation_get_size() function returns a size of the virtual reservation area. that's the whole return value. one number. main character energy, minimal effort, obsessed. ⭐
