POSIX_TRA...R_DESTROY(3P)

💖 POSIX_TRA...R_DESTROY(3P) — bestie edition 💖

okay so real talk, this page lives in the POSIX Programmer's Manual (section 3P, iykyk), and before we get into it there's a lil disclaimer you need to clock 👑

PROLOG — This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux. 💀

so like. it might not even exist on ur machine. read the room bestie.

✨ NAME ✨

posix_trace_attr_destroy, posix_trace_attr_init — destroy and initialize the trace stream attributes object (TRACING) 🦋

---

🌸 SYNOPSIS 🌸

#include <trace.h>

int posix_trace_attr_destroy(trace_attr_t *attr);
int posix_trace_attr_init(trace_attr_t *attr);

two functions, one little trace_attr_t pointer, the whole vibe. 💅

---

💜 DESCRIPTION 💜

so posix_trace_attr_destroy() is the breakup function — it shall destroy an initialized trace attributes object. and like any good breakup, there's a comeback arc: a destroyed attr attributes object can be reinitialized using posix_trace_attr_init(). but the results of otherwise referencing the object after it has been destroyed are undefined 🙈 so don't text ur ex, ok?

meanwhile posix_trace_attr_init() shall initialize a trace attributes object attr with the default value for all of the individual attributes used by a given implementation. cute, fresh start, main character energy ✨

the read-only generation-version and clock-resolution attributes of the newly initialized trace attributes object shall be set to their appropriate values (see Section 2.11.1.2, posix_trace_status_info Structure). those two are not up for debate, they come pre-set 🎀

results are undefined if posix_trace_attr_init() is called specifying an already initialized attr attributes object. like, don't double-init, that's not slay.

implementations may add extensions to the trace attributes object structure as permitted in the Base Definitions volume of POSIX.1‐2017, Chapter 2, Conformance. so ur implementation might have extra lil secrets in there 👀

here's the tea on what this object is even for: the resulting attributes object (possibly modified by setting individual attributes values), when used by posix_trace_create(), defines the attributes of the trace stream created. a single attributes object can be used in multiple calls to posix_trace_create() — reuse the fit, we love sustainability 💖

after one or more trace streams have been created using an attributes object, any function affecting that attributes object, including destruction, shall not affect any trace stream previously created. the streams already left the group chat, they're fine, they're thriving 🌈

and one more thing: an initialized attributes object also serves to receive the attributes of an existing trace stream or trace log when calling the posix_trace_get_attr() function. multitasking queen 👑

---

⭐ RETURN VALUE ⭐

upon successful completion, these functions shall return a value of zero ✨ otherwise, they shall return the corresponding error number.

---

💀 ERRORS 💀

posix_trace_attr_destroy() — may fail if:

• EINVAL — The value of attr is invalid. 🙈

posix_trace_attr_init() — shall fail if:

• ENOMEM — Insufficient memory exists to initialize the trace attributes object. 😭

the following sections are informative. (translation: not the law, just lore 🧚)

---

🍓 EXAMPLES 🍓

None. bestie the examples section is literally empty. we got nothing. moving on 😭

---

🌸 APPLICATION USAGE 🌸

None. also empty. the void. the silence. 💀

---

🦋 RATIONALE 🦋

None. nothing here either. iconic of them honestly ✨

---

🔥 FUTURE DIRECTIONS 🔥

the posix_trace_attr_destroy() and posix_trace_attr_init() functions may be removed in a future version. so like… enjoy them while they're here 🥲
