MEMCACHED_LAST_ERROR(3)

💖 MEMCACHED_LAST_ERROR 💖

okay bestie, pull up a chair, because we're about to talk about memcached_last_error from libmemcached-awesome — that's the MEMCACHED_LAST_ERROR(3) page, and it's literally just three little functions that tell you what went wrong last time. lowkey the most relatable thing in the whole library. ✨

🦋 NAME 🦋

memcached_last_error — libmemcached Documentation 🎀

---

🌸 SYNOPSIS 🌸

first things first, you gotta bring the header in:

#include <libmemcached/memcached.h>

and when you compile and link, you say:

Compile and link with -lmemcached

then we've got our three little icons 👑:

memcached_return_t memcached_last_error(const memcached_st *ptr)

• Parameters
  • ptr — pointer to an initialized memcached_st struct
• Returns
  • memcached_return_t indicating success of last operation

const char *memcached_last_error_message(const memcached_st *ptr)

• Parameters
  • ptr — pointer to an initialized memcached_st struct
• Returns
  • message describing the status of last operation

int memcached_last_error_errno(const memcached_st *ptr)

• Parameters
  • ptr — pointer to an initialized memcached_st struct
• Returns
  • errno(3) (if any) of last operation

---

✨ DESCRIPTION ✨

Retrieve error codes and messages. that's it, that's the vibe. you ask, it tells you what happened. 💅

---

🫶 RETURN VALUE 🫶

• memcached_last_error() — returns the last error code. periodt.
• memcached_last_error_message() — returns the last error message. and ooh, here's the tea: if this error came from a specific server, its hostname and port will be provided in the error message. the message comes back as a 'const char *' which does not need to be de-allocated (so don't you dare free() it, bestie 😭). and NULL will be returned if no error has occurred. no notes. 🌈
• memcached_last_error_errno() — returns any last local error code obtained from errno(3).

fr fr, that NULL case is important — no error means no message, not an empty string. 🙈

and that's the whole page, bestie, we ate and left no crumbs 🍓✨ this was libmemcached-awesome version 1.1, dated Jul 24, 2025 — and it was MEMCACHED_LAST_ERROR(3) the entire time 💜🧚 mwah, go check your error codes 🎀
