dmmp_reconfig(3)

✨ dmmp_reconfig(3) — the libdmmp manual, bestie edition ✨

okay so real talk, this is the Device Mapper Multipath API manual — the libdmmp one, section 3 — and today's main character is dmmp_reconfig(3). she's short, she's sweet, she tells the multipathd daemon to go do a little reconfiguration. slay. 💅

---

🎀 NAME 🎀

dmmp_reconfig — Instruct multipathd daemon to do reconfiguration.

like literally that's her whole job. no cap.

---

🌸 SYNOPSIS 🌸

int dmmp_reconfig (struct dmmp_context *ctx);

---

🦋 ARGUMENTS 🦋

• ctx — a pointer of 'struct dmmp_context'. and bestie, listen: if this pointer is NULL, your program will be terminated by assert. not a vibe. not even a little. so pls don't pass NULL. 🙈

---

✨ DESCRIPTION ✨

Instruct multipathd daemon to do reconfiguration. that's it, that's the whole thing. you're basically sending a lil note to the daemon like "hey queen, reconfigure for me" 💌 and she does it.

---

💖 RETURN 💖

Returns int. the valid error codes are, in no particular order but very much in a bulleted list:

• DMMP_OK
• DMMP_ERR_BUG
• DMMP_ERR_NO_MEMORY
• DMMP_ERR_NO_DAEMON
• DMMP_ERR_PERMISSION_DENY

Error number could be converted to string by dmmp_strerror. so if you get a number back and you're like "what does that even mean 😭", hit up dmmp_strerror and she'll translate. iykyk.

---

reminder bestie: keep every one of those error codes in mind, because the return value is giving int and nothing else. no guessing, just read the code. 💀
