22 Fetches a cursor containing documents, each corresponding to an index
23 on this collection.
24
25 This function is considered a retryable read operation. Upon a tran‐
26 sient error (a network error, errors due to replica set failover, etc.)
27 the operation is safely retried once. If retryreads is false in the
28 URI (see mongoc_uri_t) the retry behavior does not apply.

31 • collection: A mongoc_collection_t.
32
33 • error: An optional location for a bson_error_t or NULL.
34
36 Errors are propagated via the error parameter.
37
39 This function returns a newly allocated mongoc_cursor_t that should be
40 freed with mongoc_cursor_destroy() when no longer in use. The returned
41 mongoc_cursor_t is never NULL, even on error. The user must call
42 mongoc_cursor_next() on the returned mongoc_cursor_t to execute the
43 initial command.
44
45 Cursor errors can be checked with mongoc_cursor_error_document(). It
46 always fills out the bson_error_t if an error occurred, and optionally
47 includes a server reply document if the error occurred server-side.
48
49 WARNING:
50 Failure to handle the result of this function is a programming er‐
51 ror.
52
53 In the returned cursor each result corresponds to the server's repre‐
54 sentation of an index on this collection. If the collection does not
55 exist on the server, the cursor will be empty.
56
57 The cursor functions mongoc_cursor_set_limit(),
58 mongoc_cursor_set_batch_size(), and
59 mongoc_cursor_set_max_await_time_ms() have no use on the returned cur‐
60 sor.
