MONGOC_GRIDFS_FIND_ONE(3)

💖 MONGOC_GRIDFS_FIND_ONE 💖

okay bestie, so this one is a libmongoc classic — it lives in the mongoc_gridfs_find_one era of GridFS and it's deprecated, so buckle up 🫶

⚠️ WARNING: Deprecated since version 1.5.0: this function is deprecated, use mongoc_gridfs_find_one_with_opts() instead. no cap, it's giving "we moved on, you should too" 💀

✨ SYNOPSIS ✨

mongoc_gridfs_file_t *
mongoc_gridfs_find_one (mongoc_gridfs_t *gridfs,
                        const bson_t *query,
                        bson_error_t *error);

look at that signature, so clean, so simple, so deprecated 🌸

🎀 PARAMETERS 🎀

• gridfs — a mongoc_gridfs_t. your gridfs bestie, the whole vibe.
• query — a bson_t. the search you're doing, the thing you're looking for 💅
• error — an optional place to put a bson_error_t, or NULL if you're feeling brave and don't want the tea 🫖

---

🦋 DESCRIPTION 🦋

so basically, this function shall execute a query on the underlying gridfs implementation. the first file matching query will be returned. main character gets picked first, periodt. 👑

if there's an error, NULL is returned and error is filled out — like, fully filled out, she's not holding back 😭. but if there's no error and just no matching file? NULL is returned too, and the error code and domain are 0. sneaky, right? no error but also no file. the vibes are ambiguous 🙈

this function is considered a retryable read operation. so upon a transient error — think a network error, errors due to replica set failover, etc. — the operation is safely retried once. she gets one (1) do-over, iconic. ✨ but if retryreads is false in the URI (see mongoc_uri_t), the retry behavior does not apply. no retries for you, bestie 💀

---

🌈 ERRORS 🌈

errors are propagated via the error parameter. that's the whole system, the tea gets passed through the error slot, iykyk 🍓

---

⭐ RETURNS ⭐

a newly allocated mongoc_gridfs_file_t, or NULL if no file could be found. and listen — you must free the resulting file with mongoc_gridfs_file_destroy() if it's non-NULL. do not forget, do not ghost your memory, that's a leak and leaks are not the vibe 😤🧚
