qed_chain_produce(9)

💖 NAME 💖

qed_chain_produce — okay so this is the literal glow-up move for a chain where the driver "Produces" elements 💅 bestie, you call this to get a pointer to the next element that can be "Produced", and that's the whole vibe.

But listen — and I mean this with love — it's the driver's responsibility to validate that the chain actually has room for a new element. The function does not check for you. She is not your mom, she is not doing the vibe check on capacity, that's on you. 😭

✨ SYNOPSIS ✨

void * qed_chain_produce (struct qed_chain *p_chain );

🎀 ARGUMENTS 🎀

• p_chain — the chain. literally just the chain. that's the whole argument, she's low maintenance 🫶

🌸 RETURN 🌸

Returns void* — a pointer to the next element. iconic, no notes ✨

✨ quick reminder bestie: no capacity validation in here. check the room yourself before you produce, or it's giving undefined chaos 💀
