comedi_isad...le_on_sample(9)

💅 comedi_isadma_disable_on_sample — a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual ✨ — this one's a tiny little function from the comedi ISA DMA family and honestly it's giving "small but crucial" energy. Let's get into it 🫶

---

🌸 NAME 🌸

comedi_isadma_disable_on_sample — literally just disables the ISA DMA channel. that's the whole vibe. no cap 💅

---

⭐ SYNOPSIS ⭐

unsigned int comedi_isadma_disable_on_sample (unsigned int dma_chan ,
unsigned int size );

look at her. two args, returns an unsigned int, absolutely iconic 🔥

---

🎀 ARGUMENTS 🎀

• dma_chan — the DMA channel you're disabling, bestie. that's the one. the channel. the DMA one 💫
• size — the sample size, and yes it's measured in bytes 📏 (iykyk, units matter)

---

🦋 DESCRIPTION 🦋

so what does it actually do? it returns the residue — aka the remaining bytes — left in the DMA transfer 💖 that's it, that's the function. short and sweet, main character energy fr fr ✨
