💖 PAPI_thread_id(3) 💖

okay bestie, welcome to the PAPI manual page for PAPI_thread_id — the little function that tells you the thread identifier of the current thread. it’s giving “which thread am I?” main character energy, and we’re obsessed. 🫶

🌸 NAME 🌸

PAPI_thread_id — Get the thread identifier of the current thread.

✨ SYNOPSIS ✨

Detailed Description

🔥 Return values 🔥

• PAPI_EMISC is returned if there are no threads registered. 💀
• -1 is returned if the thread id function returns an error. 😭

This function returns a valid thread identifier. It calls the function registered with PAPI through a call to PAPI_thread_init(). no cap, that’s the whole vibe. 💅

Here’s the example, kept exactly as it is so you can trust it:

unsigned long tid;

if ((tid = PAPI_thread_id()) == (unsigned long int)-1 )
    exit(1);

printf("Initial thread id is: %lu\n", tid );
