💅 prb_rec_init_rd(9) — like, the Kernel API Manual page, bestie ✨

okay so this is prb_rec_init_rd(9) from the Kernel API Manual, and it's literally the glow-up ritual for a record-reading buffer. get comfy 🎀

🌸 NAME 🌸

prb_rec_init_rd — Initialize a buffer for reading records.

✨ SYNOPSIS ✨

void prb_rec_init_rd (struct printk_record *r , struct printk_info *info
, char *text_buf , unsigned int text_buf_size );

🫶 ARGUMENTS 🫶

• r — The record to initialize. this one's the main character, no cap 👑
• info — A buffer to store record meta-data. the ~lore~ of the record, basically 📝
• text_buf — A buffer to store text data. where the actual words go 💬
• text_buf_size — The size of text_buf. gotta know how much room the vibe has 📏

💖 DESCRIPTION 💖

So what it does is initialize all the fields that a reader is interested in. that's the whole assignment, and it ate 💅

All arguments (except r) are optional — lowkey generous of it. Only record data for arguments that are non-NULL or non-zero will be read. fr fr, if you leave one out or pass a zero, it just doesn't read that part. vibe check passed 🌈

bestie just remember: r is not optional. everything else can ghost you, but r stays 🫶
