💅 kho_block_set_it_reserve_entry(9) 💅

okay bestie, welcome to the Kernel API Manual page kho_block_se...eserve_entry(9) — this one is about kho_block_set_it_reserve_entry, and it is literally the slot-reservation girlie. ✨

✨ NAME ✨

kho_block_set_it_reserve_entry — reserve and return the next available slot for writing. 💅

🌸 SYNOPSIS 🌸

void * kho_block_set_it_reserve_entry (struct kho_block_set_it *it );

🎀 ARGUMENTS 🎀

• it — the block iterator. that's the whole argument list, no cap. 🫶

🦋 DESCRIPTION 🦋

okay so picture this: you're doing state serialization and you need to add a new entry to the current block. This function reserves a slot in the current block for exactly that, and it advances the internal index. ✨

And if the current block is full? No stress — it automatically moves to the next block in the set. 🦋

⭐ RETURN ⭐

It gives you a pointer to the reserved entry slot. But if the block set's capacity is fully exhausted, you get NULL. 😭
