sysdecode_quotactl_cmd(3)

💅 sysdecode_quotactl_cmd — from the Library Functions Manual, bestie

okay so real talk, this one lives in section 3 of the Library Functions Manual, and it's called sysdecode_quotactl_cmd. it's literally a tiny little function whose whole personality is "print the name of a quotactl command," and honestly? icon behavior. 🎀

✨ LIBRARY ✨

she's from the library “libsysdecode”, periodt. that's her home. 💖

🌸 SYNOPSIS 🌸

like, the whole vibe:

#include <sysdecode.h>

bool
sysdecode_quotactl_cmd(FILE *fp, int cmd);

🦋 DESCRIPTION 🦋

so what does sysdecode_quotactl_cmd() actually do? it takes the cmd argument — the one you'd be passing to quotactl(2) — and writes a text description of it out to the stream fp. that description is formatted as an invocation of the QCMD macro, which is defined over in the <ufs/ufs/quota.h> header. iykyk. ✨

here's the tea on the order of operations: first the function computes the primary and secondary values that QCMD uses to construct cmd. 🙈

• if the primary command value doesn't represent a known constant, sysdecode_quotactl_cmd() does not generate any output at all, and returns false. no output, no notes, nothing. 💀
• otherwise, sysdecode_quotactl_cmd() outputs text depicting an invocation of QCMD with the associated constants for the primary and secondary command values, and returns true. slay. 👑
• and if the secondary command value doesn't represent a known constant? lowkey fine, its value just gets output as a hexadecimal integer. 🧚

⭐ RETURN VALUES ⭐

the sysdecode_quotactl_cmd function returns true if it outputs a description of cmd, and false if it does not. that's the whole vibe check. 💅

🌈 EXAMPLES 🌈

okay so this statement:

sysdecode_quotatcl_cmd(stdout, QCMD(Q_GETQUOTA, USRQUOTA);

outputs the text “QCMD(Q_GETQUOTA, USRQUOTA)” to standard output. ate, no crumbs. 🔥
