okay bestie, gather round, because this is QMC(3), a section 3 library page, and she's honestly kind of a queen 👑

✨ NAME ✨

QMC — the library for managing groups of Performance Co-Pilot metrics 🎀

---

🌸 C++ SYNOPSIS 🌸

#include <qmc.h>

c++ ... -lpcp_qmc -lpcp

yes, that's really it, she's lowkey chill like that 💅

---

🦋 DESCRIPTION 🦋

so the Qt-based Performance Metrics Class (QMC) class library is literally a whole collection of C++ classes whose entire job is managing a large set of performance metrics from a variety of sources 🌈

and the way that she does all of this? she's built over PMAPI(3). that's the foundation, the blueprint, the main character she's standing on top of 👑

---

🔥 DIAGNOSTICS 🔥

okay this part matters so listen up fr fr 🙈

Error messages are generated using pmprintf(3) — but they are not flushed. not flushed!! so it is 100% the responsibility of the user to call pmflush(3) to actually output any messages.

not me forgetting to call pmflush(3) and then wondering where all my diagnostics went 💀 that's on you, bestie, the library is not gonna do it for you.

Additional diagnostics may be activated by adding the option pmc to the global debugging specification, as described in pmSetDebug(3) ✨
