msc_buffer_free(9)

💖 NAME 💖

okay so bestie, meet msc_buffer_free(9) from the Kernel API Manual — the little cleanup icon whose whole job is literally to free buffers for MSC. That’s the assignment. Slay. ✨

✨ SYNOPSIS ✨

void msc_buffer_free (struct msc *msc );

🌸 ARGUMENTS 🌸

• msc — the MSC device. yes, that one. your main-character struct for this call 🫶

🦋 DESCRIPTION 🦋

It frees MSC’s storage buffers. that’s the vibe 💅

real talk: this modifies msc::win_list and msc::base, which requires msc::buf_mutex to serialize, so the caller is expected to hold it. like, you already have the mutex, bestie — don’t show up empty-handed 🔒
