POSIX_TRACE_SET_FILTER(3P)

🦋 POSIX_TRACE_SET_FILTER(3P) 🦋

okay so bestie, welcome to the POSIX Programmer's Manual ✨ — this is the page for POSIX_TRACE_SET_FILTER(3P), and honestly? It's a short one. Like, blink-and-you-miss-it short. But we're gonna give it the full main character treatment anyway because every page deserves it 💅

🌸 PROLOG 🌸

Real talk first, because this part matters:

This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ — so please, for the love of everything, go consult the corresponding Linux manual page for the details on how Linux actually behaves. Or, plot twist, the interface may not be implemented on Linux at all 🙈. Either way: check before you ship.

Not me warning you about portability before we've even gotten to the NAME section. That's just who I am 💖

✨ NAME ✨

posix_trace_set_filter — set filter of an initialized trace stream (TRACING)

---

🎀 SYNOPSIS 🎀

#include <trace.h>

int posix_trace_set_filter(trace_id_t trid,
    const trace_event_set_t *set, int how);

Three arguments, one int coming back at you, and the whole tracing vibe. We love a compact signature 🫶

💜 DESCRIPTION 💜

okay so, here's the thing. The description is literally just this:

Refer to posix_trace_get_filter().

That's it. That's the whole description. The POSIX authors said "the explanation lives over there, go look" and honestly? Respect. Efficiency. Slay 💅

So if you want the actual deets on setting a filter on an initialized trace stream, the posix_trace_get_filter() page is your destination. This page is just the doorway, bestie 🚪✨
