msc_buffer_win_free(9)

🎀 msc_buffer_win_free(9) 🎀

okay bestie, welcome to the Kernel API Manual page for msc_buffer_win_free — the little “free a window from MSC’s window list” moment. it’s giving cleanup era, and we’re obsessed. 💅✨

✨ NAME ✨

msc_buffer_win_free — free a window from MSC's window list. no cap, that’s the whole vibe. 🦋

🌈 SYNOPSIS 🌈

void msc_buffer_win_free (struct msc *msc , struct msc_window *win );

🫶 ARGUMENTS 🫶

• msc — MSC device. the main character device in this situation. 👑
• win — window to free. bye bestie, you’re getting freed. 🎀

💅 DESCRIPTION 💅

okay so here’s the tea: this modifies msc::win_list and msc::base, which requires msc::buf_mutex to serialize, so the caller is expected to hold it. it’s giving lock-having main character energy — no cap. 🔥

⚠️ lock-vibe check, bestie: the caller is expected to hold msc::buf_mutex for this. that part is literally the requirement. 💀
