char *username, const char *password)

Parameters

• ptr — pointer to initialized memcached_st struct
• username — (yes bestie, it's just… blank in the original, I'm not hiding anything from you, that's literally all it says 🙈)
• password — (same situation, empty in the source, no cap)

Returns

memcached_return_t indicating success

🦋 DESCRIPTION 🦋

libmemcached lets you plug in your very own callbacks function, the one libsasl uses to do SASL authentication. main character energy, honestly 💅

⚠️ heads up bestie ⚠️ SASL requires the memcached binary protocol, and you have to specify the callbacks before you connect to the server. No sneaking them in after, periodt.

memcached_set_sasl_auth_data() is a lil helper function that defines the basic functionality for you — iconic, generous, we love her — but it will store the username and password in memory. If you go this route, you have to call memcached_destroy_sasl_auth_data() before calling memcached_free(), or you get a memory leak and that is not the vibe 😭

And listen: you should NOT call memcached_destroy_sasl_auth_data() if you specify your own callback function with memcached_set_sasl_callbacks(). Like, do not. Fr fr. 🫶

---

⭐ RETURN VALUE ⭐

memcached_get_sasl_callbacks() returns the callbacks currently used by this memcached handle. memcached_set_sasl_auth_data() returns MEMCACHED_SUCCESS upon success. slay ✨
