ps2_sendbyte(9)

🌸 ps2_sendbyte(9) 🌸

okay bestie, welcome to the Kernel API Manual page for ps2_sendbyte(9) — yes, the manual name is right there, we’re not copying the header line, we’re folding it in like a true icon. 💅

✨ NAME ✨

ps2_sendbyte — sends a byte to the device and wait for acknowledgement. that’s it, that’s the name, and honestly it ate. 💖

🦋 SYNOPSIS 🦋

the signature is giving “tiny but important,” and it looks exactly like this:

int ps2_sendbyte (struct ps2dev *ps2dev , u8 byte , unsigned int timeout
       );

🎀 ARGUMENTS 🎀

• ps2dev — a PS/2 device to send the data to. 🫶
• byte — data to be sent to the device. 📨
• timeout — timeout for sending the data and receiving an acknowledge. ⏳

🌈 DESCRIPTION 🌈

okay so real talk: this function doesn’t handle retransmission. nope, not it. the caller is expected to handle it when needed — that’s the whole deal, no cap. 💅

also, ps2_sendbyte can only be called from a process context. that’s the vibe check, bestie — process context only. ✨
