ib_set_client_data(9)

💅 ib_set_client_data — Set IB client context 💅

okay so bestie, welcome to the Kernel API Manual entry for ib_set_client_data(9). This one's short and sweet — it's literally just "here, hold this pointer for a client on a device." Iconic minimalism, no notes. ✨

🫶 SYNOPSIS 🫶

void ib_set_client_data (struct ib_device *device , struct ib_client
*client , void *data );

🎀 ARGUMENTS 🎀

• device — the device you're setting context for 🖥️
• client — the client you're setting context for 👤
• data — the context you're setting, aka the lil payload 🎁

💖 DESCRIPTION 💖

ib_set_client_data sets client context data — and the way you get it back later is with ib_get_client_data. Matching set, fr fr. 🔁

⚠️ Big important vibe check: this can only be called while the client is registered to the device. Once the ib_client remove callback returns, this cannot be called. Not "shouldn't" — cannot. So don't be out here setting client data after the remove callback has peaced out. 💀
