trace_seq_printf(9)

💅 trace_seq_printf ✨

okay so welcome to the Kernel API Manual bestie, section 9 — this is the one about trace_seq_printf, and honestly? she's a little legend 🫶

---

🌸 NAME 🌸

trace_seq_printf — sequence printing of trace information ✨ like, it prints your trace info into a sequence, no cap 💖

---

🎀 SYNOPSIS 🎀

void trace_seq_printf (struct trace_seq *s , const char *fmt , ... );

that's it. that's the whole vibe check 👑

---

🦋 ARGUMENTS 🦋

• s — the trace sequence descriptor, aka the whole little world she's writing into 💫
• fmt — a printf format string, yes that kind of format string, she's literally the same girl 🍓
• ... — variable arguments, the "and friends" of it all 🙈

---

⭐ DESCRIPTION ⭐

so here's the tea ☕ — the tracer can go one of two ways: use sequence operations, or use its own copy to user routines. like, two paths, one destiny 💅

to make formatting a trace simpler (because formatting is lowkey a whole thing), trace_seq_printf is the one you call — she stores your strings into a special buffer, which is s 🎀 then the output can go either way: used by the sequencer, or pulled into another buffer. flexible queen behavior honestly 👑
