π NAME π
ib_get_client_data β grab that IB client context, bestie β¨
(this one lives in the Kernel API Manual, iykyk π«Ά)
πΈ SYNOPSIS πΈ
void * ib_get_client_data (struct ib_device *device , struct ib_client
*client );
π ARGUMENTS π
deviceβ the device you wanna pull context for, like, the whole reason you're here πclientβ the client you're getting that context for π¦
β¨ DESCRIPTION β¨
Okay so real talk: ib_get_client_data hands you back the client context data that was set with ib_set_client_data. Simple. Iconic. A little getter, living its truth π
But β and this is the part where you listen β you can only call this while the client is still registered to the device. The moment the ib_client remove callback returns, this is off the table. Like, cannot be called. Periodt π No cap, don't try it.
bestie the lifetime matters here fr β registered client or nothing π
