igb_read_i2c_byte(9)

💖 NAME 💖

okay so bestie, this is igb_read_i2c_byte(9) from the Kernel API Manual 💅 and the vibe is: igb_read_i2c_byte — Reads 8 bit word over I2C. That's it, that's the serve. ✨

✨ SYNOPSIS ✨

s32 igb_read_i2c_byte (struct e1000_hw *hw , u8 byte_offset , u8
       dev_addr , u8 *data );

🎀 ARGUMENTS 🎀

• hw — pointer to hardware structure. yes bestie, the hardware struct is the main character here 🫶
• byte_offset — byte offset to read. tell it where to look, periodt.
• dev_addr — device address. the address of the device, iykyk.
• data — value read. this is the value that got read, fr fr.

🌸 DESCRIPTION 🌸

okay so it performs a byte read operation over the I2C interface at a specified device address. that's the whole plot: I2C, byte read, specified device address. iconic behavior, no notes. 💖
