print_hex_dump_bytes(9)

💅 print_hex_dump_bytes(9) — NAME 🎀

Welcome to the Kernel API Manual, bestie — this one's short and sweet and we're obsessed. print_hex_dump_bytes is literally the shorthand form of print_hex_dump_debug() with default params. That's it. That's the whole personality. 🦋

✨ SYNOPSIS ✨

print_hex_dump_bytes (prefix_str , prefix_type , buf , len );

Yes, the spacing is exactly like that, don't come for me. 🙈

---

🫶 ARGUMENTS 🫶

• prefix_str — the string you want prefixed onto each line; the caller supplies trailing spaces for alignment if desired, i.e. the padding is your job, not the function's, no cap 💅
• prefix_type — controls whether a prefix of an offset, address, or none at all gets printed — your options are DUMP_PREFIX_OFFSET, DUMP_PREFIX_ADDRESS, DUMP_PREFIX_NONE 🎀
• buf — the data blob to dump, the main character of this whole operation 💖
• len — number of bytes in the buf, so it knows how much of the blob to actually spill 🌸

---

🌈 DESCRIPTION 🌈

Okay so real talk: it calls print_hex_dump_debug, with log level of KERN_DEBUG, rowsize of 16, groupsize of 1, and ASCII output included. That's the whole tea — those defaults are doing all the work and they ate. 🔥
