  • man — the command buffer manager. that's it. that's the whole argument. she's the main character here 👑

💖 DESCRIPTION 💖

So basically: this flushes the current command buffer without allocating a new one. no cap. the new one gets allocated automatically later, whenever it's actually needed — so don't stress about it, she handles herself ✨

⚠️ ok this is the part where you listen: you gotta call this with man->cur_mutex held. like, already locked by you. not "I'll lock it in a sec". held. periodt. 💅
