PARAMETERS

  • bucket: A mongoc_gridfs_bucket_t.
  • file_id: A bson_value_t specifying the id of the created file.
  • filename: The name of the file to create.
  • opts: A bson_t or NULL.
  • error: A bson_error_t to receive any error or NULL.

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.

DESCRIPTION

Opens a stream for writing to a new file in GridFS for a specified file id. To have libmongoc generate an id, use mongoc_gridfs_bucket_open_upload_stream().

RETURNS

A mongoc_stream_t that can be written to or NULL on failure. Errors on this stream can be retrieved with mongoc_gridfs_bucket_stream_error(). After calling mongoc_stream_close() the file is completely written in GridFS.
