rvt_qp_iter_init(9)

🌸 NAME 🌸

rvt_qp_iter_init — initial for QP iteration. Welcome to rvt_qp_iter_init(9), from the Kernel API Manual, bestie — yes we are in the kernel docs and the vibes are immaculate ✨

🦋 SYNOPSIS 🦋

struct rvt_qp_iter * rvt_qp_iter_init (struct rvt_dev_info *rdi , u64 v
, void (*cb)(struct rvt_qp *qp, u64 v) );

That's the exact signature, comma spacing and all — it's literally the manual's house style 💅

🎀 ARGUMENTS 🎀

• rdi — the rvt devinfo. Like, the devinfo in question, bestie.
• v — a u64 value. Sixty-four bits of "here's a value," lowkey.
• cb — user-defined callback. Your callback, your rules, fr fr.

💜 DESCRIPTION 💜

This returns an iterator suitable for iterating QPs in the system. No cap: an iterator, for QPs, in the system. Iconic.

The cb is a user-defined callback, and v is a 64-bit value passed to and relevant for processing in the cb. An example use case would be to alter QP processing based on criteria not part of the rvt_qp. iykyk.

🚨 Real talk: use cases that require memory allocation to succeed must preallocate appropriately. This is not a "we'll figure it out in the callback" situation, bestie — preallocate appropriately, periodt.

👑 RETURN 👑

Returns a pointer to an rvt_qp_iter or NULL. That's it. That's the return: a pointer or NULL, and that's the whole mood.
