lpfc_idiag_queacc_read_qe(9)

💖 NAME 💖

okay bestie, welcome to lpfc_idiag_queacc_read_qe(9) from the Kernel API Manual ✨ this page is all about reading a single entry from the given queue index — lowkey iconic, no cap. 💅

✨ SYNOPSIS ✨

int lpfc_idiag_queacc_read_qe (char *pbuffer , int len , struct lpfc_queue *pque , uint32_t index );

🎀 ARGUMENTS 🎀

• pbuffer — the pointer to the buffer where the read data gets copied into. it's giving “put the data right here” energy 💖
• len — length of the buffer. gotta know how much room we're working with, fr fr 🫶
• pque — the pointer to the queue that's getting read. main character queue energy 👑
• index — the index into the queue entry. like, which spot are we peeking at? 👀

🦋 DESCRIPTION 🦋

okay so this routine reads out a single entry from the given queue's index location and copies it into the buffer provided. that's the vibe: one entry from the queue, dropped into your buffer, periodt. 💖

🔥 RETURN 🔥

this function returns 0 when it fails, otherwise it returns the length of the data read into the buffer provided. so yeah: fail = 0, otherwise it hands back the length of what got read. slay. ✨
