cbus_transfer(9)

🦋 cbus_transfer(9) 🦋

okay bestie, welcome to the cbus_transfer(9) page from the Kernel API Manual. this one is short and sweet, and it's literally about transferring data over the bus. let's get into it 💅

💖 NAME 💖

cbus_transfer — transfers data over the bus. that's the whole job, no cap 🚌✨

✨ SYNOPSIS ✨

here's the exact signature, bestie — character for character:

int cbus_transfer (struct cbus_host *host , char rw , unsigned dev ,
       unsigned reg , unsigned data );

🎀 ARGUMENTS 🎀

• host — the host we're using. this is our main character host, periodt 🫶
• rw — read/write flag. it tells the function which direction we're going, read/write vibes 💫
• dev — device address. the address of the device, slay 📍
• reg — register address. the address of the register, iconic ✨
• data — if rw == I2C_SBUS_WRITE, this is the data to send; otherwise it's 0. so write mode gets the actual payload, and every other time it's zero, iykyk 💾
