PAPI_multiplex_init(3)

🌸 NAME 🌸

okay so bestie, welcome to the PAPI_multiplex_init(3) page from the PAPI manual — this is where we talk about initializing multiplex support in the PAPI library 💅✨

PAPI_multiplex_init is the routine that initializes multiplex support inside PAPI. Iconic, lowkey essential if you’re multiplexing, and totally skippable if you’re not.

✨ SYNOPSIS ✨

💫 Detailed Description 💫

Calling PAPI_multiplex_init() enables and initializes multiplex support in the PAPI library. Multiplexing is the whole trick that lets a user count more events than the total number of physical counters by time-sharing the existing counters — yes, with some loss in precision, that’s the tradeoff, no cap 😭

Applications that make no use of multiplexing do not need to call this routine. Literally skip it, bestie, it’s not for you 🫶

🎀 C Interface 🎀

The C interface is giving:

#include <papi.h>
int PAPI_multiplex_init (void);

🍓 Examples 🍓

Like this, bestie:

retval = PAPI_multiplex_init();

🧚 Return values 🧚

• PAPI_OK — this call always returns PAPI_OK. That’s the whole menu, periodt 💀
