MONGOC_GRIDFS...OWNLOAD_STREAM(3)

💅 MONGOC_GRIDFS...OWNLOAD_STREAM(3)

okay bestie, so this one lives in libmongoc and it's lowkey one of the most useful little functions in the whole GridFS saga — it hands you a stream so you can read a file back out. no cap. let's get into it 🫶

---

✨ SYNOPSIS ✨

mongoc_stream_t *
mongoc_gridfs_bucket_open_download_stream (mongoc_gridfs_bucket_t *bucket,
                                           const bson_value_t *file_id,
                                           bson_error_t *error);

literally just three things in, one stream out. iconic signature tbh 🎀

---

🌸 PARAMETERS 🌸

• bucket — a mongoc_gridfs_bucket_t. this is your bucket, your main character. it's where the file lives 🪣
• file_id — a bson_value_t holding the id of the file you wanna download. so you gotta know which file, bestie, no vibes-based guessing 💖
• error — a bson_error_t that catches any error, or NULL if you're feeling brave and don't want the receipt 🙈

---

🦋 DESCRIPTION 🦋

Opens a stream for reading a file from GridFS. that's the whole vibe check ✨ you get a stream, you read from it, you're living your best life. everything you need to pull a file down, no extra steps.

---

👑 RETURNS 👑

A mongoc_stream_t that can be read from, or NULL on failure 😭 — and yeah, NULL means something went sideways, so don't just ignore it.

Errors on this stream can be retrieved with mongoc_gridfs_bucket_stream_error(). so when it's giving nothing but NULL, that's your girl for the actual tea 💀
