💖 PTHREAD_SELF(3POSIX) 💖

okay bestie, welcome to the POSIX Programmer's Manual — this page is PTHREAD_SELF(3POSIX) and it's literally the shortest lil glow-up in the whole pthread family. 🦋

✨ PROLOG ✨

so before we even start — heads up, girlypop:

  • This manual page is part of the POSIX Programmer's Manual.
  • The Linux implementation of this interface may differ — so if you're on Linux, go consult the corresponding Linux manual page for the deets on Linux behavior.
  • Orrrr the interface may not be implemented on Linux at all. 🙈 iykyk.

🌸 NAME 🌸

pthread_self — get the calling thread ID 💅

🎀 SYNOPSIS 🎀

#include <pthread.h>

pthread_t pthread_self(void);

no arguments, no drama, just vibes. periodt. ✨

💜 DESCRIPTION 💜

The pthread_self() function shall return the thread ID of the calling thread.

that's it. that's the whole function. she's a one-liner icon and we stan. 👑

🌈 RETURN VALUE 🌈

pthread_self() shall always be successful. always. there is no return value reserved to indicate an error. she simply cannot fail, main character energy fr fr. 🔥

💀 ERRORS 💀

No errors are defined.

like, none. zero. the error list is empty bestie, there is nothing to check. 😭

The following sections are informative.

🧚 EXAMPLES 🧚

None.

(yeah, none. she's self-explanatory. literally.)

🍓 APPLICATION USAGE 🍓

None.

⭐ RATIONALE ⭐

okay so here's the lore 🫶 — pthread_self() provides a capability similar to the getpid() function for processes, and the rationale is the same: the creation call does not provide the thread ID to the created thread.

so like, when a thread gets born, nobody hands it its own ID. rude tbh. so it has to ask. that's her job. 💅

🦋 FUTURE DIRECTIONS 🦋

None.
