💖 tsi721_omsg_handler 💖

okay so bestie, welcome to the tsi721_omsg_handler(9) page from the Kernel API Manual — yes that's the manual name, we're being official today 💅 this one's a tiny little function but she's got a huge SEE ALSO section, so buckle up 🎀

✨ NAME ✨

tsi721_omsg_handler — Outbound Message Interrupt Handler 👑

🌸 SYNOPSIS 🌸

void tsi721_omsg_handler (struct tsi721_device *priv , int ch );

like, that's the whole signature. two args. no return value. she just does things 😌

🦋 ARGUMENTS 🦋

• priv — pointer to tsi721 private data. it's the lil' home base struct for the device, y'know? 🏠
• ch — number of OB MSG channel to service. yes, "OB MSG" = outbound message, we're abbreviating, it's fine, iykyk 💫

🔥 DESCRIPTION 🔥

Services channel interrupts from outbound messaging engine. that's it. that's the whole description and honestly? iconic. she shows up, she handles the interrupt on the channel, she leaves. main character energy fr fr 💅✨

ngl there is literally nothing else in the description section, so don't come for me — i'm not gonna invent behaviour that the page doesn't state 🙈

💜 SEE ALSO 💜
