opts may be NULL or a BSON document with additional command options:

  • chunkSizeBytes: An int32 chunk size to use for this file. Overrides the chunkSizeBytes set on bucket.

  • metadata: A bson_t representing metadata to include with the file.


Reads from the source stream and writes to a new file in GridFS. The file id is generated automatically. To specify an explicit file id, use mongoc_gridfs_bucket_upload_from_stream_with_id().

Reads from the source stream using mongoc_stream_read() until the return value indicates end-of-file. The source stream is not closed after calling mongoc_gridfs_bucket_upload_from_stream(); call mongoc_stream_close() after.


True if the operation succeeded. False otherwise and sets error.
