16 • db: A mongoc_database_t.
17
18 • opts: A bson_t or NULL
19
20 • read_prefs: A mongoc_read_prefs_t used for read operations or NULL to
21 inherit read preferences from db.
22
23 • error: A bson_error_t or NULL.

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

30 ters. See the manual for the max namespace length.
31
32 • chunkSizeBytes: An int32 representing the chunk size. Defaults to
33 255KB.
34
35 • writeConcern: Construct a mongoc_write_concern_t and use
36 mongoc_write_concern_append() to add the write concern to opts. See
37 the example code for mongoc_client_write_command_with_opts().
38
39 • readConcern: Construct a mongoc_read_concern_t and use
40 mongoc_read_concern_append() to add the read concern to opts. See the
41 example code for mongoc_client_read_command_with_opts(). Read concern
42 requires MongoDB 3.2 or later, otherwise an error is returned.
