LIBPFM(3)

💖 LIBPFM(3) 💖

omg bestie you made it to the very last page of the Linux Programmer's Manual arc, and it's literally the goodbye episode 😭 This is LIBPFM(3), and today's main character is pfm_terminate — the little function that closes the tab on your perfmon era. 🎀

✨ NAME ✨

pfm_terminate — free resources used by library 🧚

no cap, that's the whole job description and she does it flawlessly.

🌸 SYNOPSIS 🌸

#include <perfmon/pfmlib.h>

int pfm_terminate(void);

yes bestie, that's the exact signature, copy it character for character, do NOT freestyle it 💅

🦋 DESCRIPTION 🦋

Okay so listen. 👑

This is the last function that a program must call — like, must must, not optional must — to free all the resources allocated by the library, e.g., memory. 🌈 Think of it as the cleanup crew that shows up after the party and takes the balloons down. If you skip it, the balloons just stay there. Forever. Not cute. 🙈

⚠️ Vibe check, important: the function is not reentrant. The caller must ensure only one thread at a time is executing it. So no letting two threads yank the same cord at the same time, that's giving chaos energy and we do not stan. 🫶

⭐ RETURN ⭐

There is no return value to this function. 💀

She says nothing. She simply leaves. Iconic behavior, honestly. Periodt. ✨
