dmmp_strerror(3)

✨ dmmp_strerror ✨

okay bestie, so this one lives in the Device Mapper Multipath API - libdmmp Manual and it's genuinely one of the most useful little functions in the whole libdmmp situation, i promise 🫶 it's dmmp_strerror from section 3, and what it does is take a sad little error number and turn it into actual words you can read. no cap.

🌸 NAME 🌸

dmmp_strerror — bestie, it converts an error code into a string. that's it. that's the whole job. iconic 💅

---

🎀 SYNOPSIS 🎀

const char * dmmp_strerror (int rc);

---

🦋 ARGUMENTS 🦋

• rc — an int. this is the return code you got back from libdmmp functions, like the little receipts of "hey something happened". and here's the tea: if the error code you hand over isn't actually a valid error code, it just gives you back "Invalid argument". so rude of you, but it's very polite about it 💖

---

💜 DESCRIPTION 💜

so basically: it takes an error code (int) and converts it to a string (const char *). the way that a number becomes a whole sentence? obsessed. here's the full conversion chart, no details skipped, periodt:

• DMMP_OK — "OK"
• DMMP_ERR_BUG — "BUG of libdmmp library" 😭
• DMMP_ERR_NO_MEMORY — "Out of memory" 💀
• DMMP_ERR_IPC_TIMEOUT — "Timeout when communicate with multipathd, try to set bigger timeout value via dmmp_context_timeout_set ()"
• DMMP_ERR_IPC_ERROR — "Error when communicate with multipathd daemon"
• DMMP_ERR_NO_DAEMON — "The multipathd daemon not started" 🙈
• DMMP_ERR_INCOMPATIBLE — "The multipathd daemon version is not compatible with current library"
• any other invalid error number — "Invalid argument"

not me listing every single one because skipping options is literally a crime in this house 🚨

---

⭐ RETURN ⭐

returns a const char *. it's the meaning of the error code you provided. like a translator but for vibes and errno-adjacent drama. 🧚
