ps2_drain(9)

🌸 NAME 🌸

okay so welcome to the Kernel API Manual page for ps2_drain(9), bestie! ps2_drain waits for the device to transmit the requested number of bytes and discards them. no cap, that's the whole name-summary. 💅

✨ SYNOPSIS ✨

here's the signature, copy-paste ready and everything:

void ps2_drain (struct ps2dev *ps2dev , size_t maxbytes , unsigned int timeout );

💅 ARGUMENTS 💅

• ps2dev — the PS/2 device that should be drained. this is the main character you're targeting, bestie.
• maxbytes — maximum number of bytes to be drained. it's the cap, the limit, the "don't do more than this" number.
• timeout — time to drain the device. yes ma'am.
