✨ SYNOPSIS ✨

that's the whole signature, exactly like that, don't @ me 🎀

🎀 ARGUMENTS 🎀

  • chan — the bam dma channel. that's the one. the main character of this function 🌟

💖 DESCRIPTION 💖

So what actually happens here? Bestie, it dequeues and frees all transactions. All of them. Gone. Dequeued AND freed, both things, in that order, no survivors 🧹✨

And the important part — like, genuinely important, don't skip this — No callbacks are done. None. Zero. Not a single callback. So if you were sitting there waiting for a callback to fire, uh, she's not coming 😭. That's just how it is, fr fr.
