POSIX_SPA..._GETPGROUP(3P)

💅 POSIX_SPA..._GETPGROUP(3P) 💅

okay bestie, welcome to the POSIX Programmer's Manual — this page lives in that family, and it's giving POSIX_SPA..._GETPGROUP(3P) energy. ✨

🌸 PROLOG 🌸

This manual page is part of the POSIX Programmer's Manual. Heads up tho: the Linux implementation of this interface may differ (so like, go read the corresponding Linux manual page if you need the Linux tea 🫖), or honestly the interface may not even be implemented on Linux. No cap.

✨ NAME ✨

posix_spawnattr_getpgroup, posix_spawnattr_setpgroup — get and set the spawn-pgroup attribute of a spawn attributes object (ADVANCED REALTIME) 👑

---

🎀 SYNOPSIS 🎀

#include <spawn.h>

int posix_spawnattr_getpgroup(const posix_spawnattr_t *restrict attr,
    pid_t *restrict pgroup);
int posix_spawnattr_setpgroup(posix_spawnattr_t *attr, pid_t pgroup);

---

🦋 DESCRIPTION 🦋

So posix_spawnattr_getpgroup() shall obtain the value of the spawn-pgroup attribute from the attributes object referenced by attr. She's just reading the vibe, okay? 💖

And posix_spawnattr_setpgroup() shall set the spawn-pgroup attribute in an initialized attributes object referenced by attr. Setting the vibe, iconic behavior.

The spawn-pgroup attribute represents the process group to be joined by the new process image in a spawn operation — but ONLY if POSIX_SPAWN_SETPGROUP is set in the spawn-flags attribute, iykyk. The default value of this attribute shall be zero.

---

🔥 RETURN VALUE 🔥

Upon successful completion, posix_spawnattr_getpgroup() shall return zero and store the value of the spawn-pgroup attribute of attr into the object referenced by the pgroup parameter. Otherwise, an error number shall be returned to indicate the error. 😭

Upon successful completion, posix_spawnattr_setpgroup() shall return zero; otherwise, an error number shall be returned to indicate the error.

---

💀 ERRORS 💀

These functions may fail if:

• EINVAL — the value specified by attr is invalid.

The posix_spawnattr_setpgroup() function may fail if:

• EINVAL — the value of the attribute being set is not valid.

The following sections are informative. (yes literally, that's the note, keep reading bestie)

🌈 EXAMPLES 🌈

None. 😌 (not a single one, we're keeping it real)

---

🍓 APPLICATION USAGE 🍓

These functions are part of the Spawn option and need not be provided on all implementations. So like, vibe check your platform first, fr fr.

🧚 RATIONALE 🧚

None.

⭐ FUTURE DIRECTIONS ⭐

None.
