POSIX_SPAWNATTR_GETSCHEDPOLICY(3)

hey bestie 💖 you've landed on POSIX_SPAWNATTR_GETSCHED(3) from the Library Functions Manual, and it's lowkey iconic: this page is all about getting and setting the spawn-schedpolicy attribute of a spawn attributes object. no cap, it's giving scheduler-nerd realness and i'm here for it.

💖 NAME 💖

• posix_spawnattr_getschedpolicy
• posix_spawnattr_setschedpolicy

these two besties get and set the spawn-schedpolicy attribute of a spawn attributes object. that's the whole vibe. ✨

🦋 LIBRARY 🦋

Standard C Library (libc, -lc) — yup, that's where these functions live, bestie.

✨ SYNOPSIS ✨

#include <spawn.h>

int
posix_spawnattr_getschedpolicy(const posix_spawnattr_t *restrict attr,
    int *restrict schedpolicy);

int
posix_spawnattr_setschedpolicy(posix_spawnattr_t *attr,
    int schedpolicy);

🌸 DESCRIPTION 🌸

so posix_spawnattr_getschedpolicy() is the getter gf: she obtains the value of the spawn-schedpolicy attribute from the attributes object referenced by attr. she's not messy, she just reads the vibe and reports back. 🫶

then posix_spawnattr_setschedpolicy() is the setter bf: he sets the spawn-schedpolicy attribute in an initialized attributes object referenced by attr. key word: initialized, bestie — don't come at him with an uninitialized object and expect magic. 💅

the spawn-schedpolicy attribute represents the scheduling policy that's going to be assigned to the new process image in a spawn operation — but only if POSIX_SPAWN_SETSCHEDULER is set in the spawn-flags attribute. so like, it's conditional slay. the default value of this attribute is unspecified, which is the manpage way of saying "we're not telling, go check your implementation." 💀

🎀 RETURN VALUES 🎀

both posix_spawnattr_getschedpolicy() and posix_spawnattr_setschedpolicy() return zero. that's it. that's the whole return value. zero. no drama, no surprises, just zero. periodt. 🎀

👑 STANDARDS 👑

posix_spawnattr_getschedpolicy() and posix_spawnattr_setschedpolicy() conform to IEEE Std 1003.1-2001 (“POSIX.1”). standards queen behavior, honestly. 🌈

🌈 HISTORY 🌈

these two functions first appeared in FreeBSD 8.0. so they've been serving since way back. vintage but still relevant, like a good pair of low-rise jeans. 🦋
