xenbus_read_driver_state(9)

💖 NAME 💖

okay so bestie, welcome to the xenbus_read_driver_state(9) page — yes, it’s giving Kernel API Manual energy, and the whole assignment is: read state from a store path. that’s it, that’s the name, no cap. ✨

🦋 SYNOPSIS 🦋

like, the function signature is literally this, keep it cute and exact:

enum xenbus_state xenbus_read_driver_state (const struct xenbus_device
       *dev , const char *path );

🎀 ARGUMENTS 🎀

• dev — xenbus device pointer, the device bestie we’re passing in. 🫶
• path — path for driver, the driver path situation. 💅

💅 RETURN 💅

it returns the state of the driver rooted at the given store path, or XenbusStateUnknown if no state can be read. that’s the whole return vibe, periodt. 👑

bestie note: if no state can be read, it’s XenbusStateUnknown — literally in the return description, iykyk. 🙈
