Q_XGETQUOTA(2const)

👑 Q_XGETQUOTA — get quota limits for an XFS filesystem

okay bestie, welcome to Q_XGETQUOTA, a little constant from the (2const) manual-page corner of the universe 🌈 she's not a whole function, she's the type you hand to the quotactl girlies so they know exactly which quota-flavored move you're making. let's get into it 💅

🌸 NAME

Q_XGETQUOTA — get quota limits for an XFS filesystem ✨

---

📚 LIBRARY

Standard C library (libc, -lc) 🎀

like, she's right there in libc, no cap.

🦋 SYNOPSIS

#include <xfs/xqm.h>      /* See quotactl(2) */
#include <sys/quota.h>

int quotactl(QCMD(Q_XGETQUOTA, type), const char *_Nullable special,
             int id, caddr_t addr);

#include <xfs/xqm.h>      /* See quotactl_fd(2) */
#include <sys/syscall.h>  /* Definition of SYS_* constants */
#include <unistd.h>

int syscall(SYS_quotactl_fd, int fd, QCMD(Q_XGETQUOTA, type),
            int id, struct fs_disk_quota *addr);

two whole vibes: the classic quotactl(2) path, or the fd-based quotactl_fd(2) path via syscall(2). pick your fighter 🫶

💖 DESCRIPTION

Get disk quota limits and current usage for user id. periodt. 👑

The addr argument is a pointer to an fs_disk_quota(2type) structure. that's where the tea gets poured 🍓

Unprivileged users may retrieve only their own quotas; a privileged user (CAP_SYS_ADMIN) may retrieve the quotas of any user. so like — if you don't have the crown, you only get to peek at your own stats, sorry babe 😭👑

ngl the return value and errors sections are literally just "go read quotactl(2)" and honestly? iconic. she's outsourcing the drama 🙈 go read the main page, bestie, the details live there.

and that's the whole page, fr fr — this was Linux man-pages 6.20, dated 2026-06-05, aka the Q_XGETQUOTA(2const) era. mwah 💋 slay, stay quotalicious, and go check your limits 🦋💜
