Q_GETFMT(2const)

✨ Q_GETFMT — get quota format ✨

okay bestie, welcome to Q_GETFMT(2const) 💖 this one lives in the 2const section of the manual (that's the "constants and stuff that goes with syscalls" corner of the man-pages world, iykyk). it's short, it's sweet, it's giving "one job, done right" 👑

🌸 LIBRARY

Standard C library (libc, -lc) 🎀 yes the regular one, no funny business.

🦋 SYNOPSIS

#include <sys/quota.h>

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

#include <sys/quota.h>    /* Definition of Q_* constants */
#include <sys/syscall.h>  /* Definition of SYS_* constants */
#include <unistd.h>

int syscall(SYS_quotactl_fd, int fd, QCMD(Q_GETFMT, type), int id,
            int32_t *addr);

two flavors, same energy fr fr 💅

💜 DESCRIPTION

Get quota format used on the specified filesystem. that's it, that's the whole vibe 🌈

the addr argument should be a pointer to a 4-byte buffer where the format number will be stored 📥 like, you hand it a little 4-byte parking spot and it parks the format number there. no cap.
