MEMCACHED_VERSION(3)

💅 MEMCACHED_VERSION — the libmemcached glow-up guide 💅

okay bestie, this is MEMCACHED_VERSION(3), living under the libmemcached-awesome umbrella. it's two little functions that tell you which libmemcached you're running and which memcached servers you're talking to. short page, big main character energy. let's go 🫶

---

✨ NAME ✨

memcached_version — literally just the libmemcached documentation, no cap 💖

---

🌸 SYNOPSIS 🌸

#include <libmemcached/memcached.h>

and like, compile and link with -lmemcached, obviously.

const char *memcached_lib_version(void)

Returns

• version string of libmemcached

memcached_return_t memcached_version(memcached_st *ptr)

Parameters

• ptr — pointer to initialized memcached_st struct

Returns

• memcached_return_t indicating success

---

🦋 DESCRIPTION 🦋

so memcached_lib_version() returns a cute little version string that represents the libmemcached version. and bestie, pay attention here: that's the client library, not the server. two different girlies entirely, don't mix them up 💀

meanwhile memcached_version() sets the major, minor, and micro versions of every single memcached server being used by the memcached_st connection structure. it hands you back the memcached server return code. periodt ✨

---

👑 RETURN VALUE 👑

memcached_lib_version() gives you a string with the version of the libmemcached driver. iconic behavior.

a value of memcached_return_t is returned from memcached_version.

on success that value will be MEMCACHED_SUCCESS. slay.

but ngl, if you call it with the MEMCACHED_BEHAVIOR_USE_UDP behavior set, you're getting MEMCACHED_NOT_SUPPORTED back. it's giving "not me, not today" 🙈

and if you want to turn that value into something a human can actually read, use memcached_strerror() to translate it into a printable string. iykyk 💜
