mhi_get_cha...rbell_offset(9)

💅 mhi_get_channel_doorbell_offset(9) — NAME

okay so this is mhi_get_channel_doorbell_offset — it gets the channel doorbell offset, bestie. that's the whole vibe. it's a Kernel API Manual entry, and honestly? she's serving quiet-luxury utility. ✨

🎀 SYNOPSIS

int mhi_get_channel_doorbell_offset (struct mhi_controller *mhi_cntrl ,
       u32 *chdb_offset );

🦋 ARGUMENTS

• mhi_cntrl — the MHI controller, like, the main character of this whole situation 👑
• chdb_offset — read channel doorbell offset here. it's a pointer, so she's writing into this — the channel doorbell offset lands in it 🎯

🌸 RETURN

0 if the read succeeds. if it doesn't? a negative error code, no cap 😭 that's it, that's the contract.

💖 SEE ALSO

literally all her friends, defined in the kernel file ./include/linux/mhi.h — go say hi 🫶
