💅 MONGOC_WRITE_CONCERN_SET_WTAG 💅

okay so bestie, this page lives in the libmongoc manual (yes, the C driver one), and it's about one tiny function that sets one tiny string. but it's a load-bearing string, so pay attention 🎀

✨ SYNOPSIS ✨

void
mongoc_write_concern_set_wtag (mongoc_write_concern_t *write_concern,
                               const char *tag);

that's it. that's the whole signature. no return value, no drama, just vibes and a void. 💜

🌸 PARAMETERS 🌸

  • write_concern — a mongoc_write_concern_t. like, the write concern struct you're editing. it's the main character here 👑
  • tag — a string holding the write tag. literally just the tag name, bestie 🏷️

🦋 DESCRIPTION 🦋

so what does it do? it sets the write tag that must be satisfied for the write to indicate success. that's the whole assignment. no cap. 🔥

write tags, for the uninitiated, are preset write concerns configured on your MongoDB server — iykyk. you don't invent them client-side, they already exist over there and you're just pointing at one by name. for more info on this setting, go look at mongoc_write_concern_t, that's where the lore lives 📚

now here's the glow-up moment: beginning in version 1.9.0, this function can now alter the write concern after it has been used in an operation. iconic behaviour change, honestly ✨

before that? 😭 previously, using the struct with an operation would mark it as "frozen" and calling this function would log a warning instead of altering the write concern. frozen. like, literally locked in place, popsicle style 🧊 so if you're on an old version and your tag mysteriously didn't take, that's why — check the warnings, she was trying to tell you 🙈
