🦋 DESCRIPTION 🦋

so here's the tea 🍓 — libmemcached lets you store a pointer to your own user specific data right inside the memcached_st structure. like, it's your little corner of the struct, your locker, your emotional support pointer. no cap. 💅

memcached_set_user_data() is the one you call to set the user specific data in the memcached_st structure. that's it. that's the job.

memcached_get_user_data() is the one you call to retrieve the user specific data from the memcached_st structure. the way these two are literally a matched set 😭🫶

---

👑 RETURN VALUE 👑

memcached_set_user_data() returns the previous value of the user specific data. yes bestie, it hands you back the old one — lowkey thoughtful.

memcached_get_user_data() returns the current value of the user specific data. as it should. ⭐
