MONGOC_APM_SET...OGY_CHANGED_CB(3)

Hey bestie 💖 you just opened the MONGOC_APM_SET...OGY_CHANGED_CB(3) manual page from libmongoc. This is the one where you set the callback that gets pinged when the server topology does something. It’s giving monitoring main character energy, no cap. 👑

✨ SYNOPSIS ✨

typedef void (*mongoc_apm_topology_changed_cb_t) (
   const mongoc_apm_topology_changed_t *event);

void
mongoc_apm_set_topology_changed_cb (mongoc_apm_callbacks_t *callbacks,
                                    mongoc_apm_topology_changed_cb_t cb);

Okay so what does it actually do? You receive an event notification whenever the driver observes a change in any of the servers it is connected to or a change in the overall server topology. That’s the whole vibe: topology watch, but make it callback. 👀✨

🎀 PARAMETERS 🎀

• callbacks — a mongoc_apm_callbacks_t. That’s the callbacks object you’re working with, bestie.
• cb — a function to call with a mongoc_apm_topology_changed_t whenever the driver observes a change in any of the servers it is connected to or a change in the overall server topology. Yes, it’s the star of the show. 🌟
