trace_print_hex_seq(9)

✨ NAME ✨

okay bestie, welcome to trace_print_hex_seq(9) from the Kernel API Manual — this one is literally “print buffer as hex sequence.” That’s the whole vibe. 💅

🌸 SYNOPSIS 🌸

const char * trace_print_hex_seq (struct trace_seq *p , const unsigned char *buf , int buf_len , bool concatenate );

🎀 ARGUMENTS 🎀

• p — the trace seq struct you’re writing to. It’s the destination, the main character energy.
• buf — the buffer to print. The actual bytes, serving looks.
• buf_len — length of buf in bytes. Gotta know how much we’re working with, fr fr.
• concatenate — print buf as a single hex string or with spacing. This flag is lowkey the whole plot.

💖 DESCRIPTION 💖

So it prints the buffer you pass in as a hex sequence. If concatenate is true, it prints the buffer as a whole, single hex string — one unbroken hex moment. If concatenate is false, it prints with spacing after each byte — little byte-by-byte breathing room. Periodt. ✨
