idpf_rx_post_buf_desc(9)

🌸 NAME 🌸

okay bestie, welcome to the idpf_rx_post_buf_desc(9) page from the Kernel API Manual 💖✨

idpf_rx_post_buf_desc — Post buffer to bufq descriptor ring. that's the whole assignment, no cap.

✨ SYNOPSIS ✨

bool idpf_rx_post_buf_desc (struct idpf_buf_queue *bufq , u16 buf_id );

🎀 ARGUMENTS 🎀

• bufq — the buffer queue to post to. literally the destination vibe.
• buf_id — the buffer id to post. the little ID card for the buffer.

💖 RETURN 💖

Returns false if the buffer could not be allocated, and true otherwise. so: false = allocation said nope 😭, true = we're so back 🫶.
