thc_tic_pio_read(9)

💖 NAME 💖

thc_tic_pio_read — Read data from touch device by PIO. This is the thc_tic_pio_read(9) page from the Kernel API Manual, and it's here to explain reading data from a touch device through PIO. Bestie, we are so ready. ✨

📜 SYNOPSIS 📜

Here's the exact signature, no cap:

int thc_tic_pio_read (struct thc_device *dev , const u32 address , const
u32 size , u32 *actual_size , u32 *buffer );

🫶 ARGUMENTS 🫶

• dev — the pointer of THC private device context. It's giving main character pointer energy for the THC private device context. 💅
• address — slave address for the PIO operation.
• size — expected read data size.
• actual_size — the pointer of the actual data size read from touch device.
• buffer — the pointer of data buffer to store the data read from touch device.

🎀 RETURN 🎀

0 on success, other error codes on failed. So success is 0 💚, and failed is other error codes on failed 😭. That's the whole return vibe check.
