16 This function is deprecated and should not be used in new code.
17
18 Please use mongoc_collection_find_indexes_with_opts() instead.
19
20 Fetches a cursor containing documents, each corresponding to an index
21 on this collection.
22
23 This function is considered a retryable read operation. Upon a tran‐
24 sient error (a network error, errors due to replica set failover, etc.)
25 the operation is safely retried once. If retryreads is false in the
26 URI (see mongoc_uri_t) the retry behavior does not apply.
27
29 • collection: A mongoc_collection_t.
30
31 • error: An optional location for a bson_error_t or NULL.
32
34 Errors are propagated via the error parameter.
35
37 This function returns a newly allocated mongoc_cursor_t that should be
38 freed with mongoc_cursor_destroy() when no longer in use. The returned
39 mongoc_cursor_t is never NULL, even on error. The user must call mon‐
40 goc_cursor_next() on the returned mongoc_cursor_t to execute the ini‐
41 tial command.
42
43 Cursor errors can be checked with mongoc_cursor_error_document. It al‐
44 ways fills out the bson_error_t if an error occurred, and optionally
45 includes a server reply document if the error occurred server-side.
46
47 WARNING:
48 Failure to handle the result of this function is a programming er‐
49 ror.
50
51 In the returned cursor each result corresponds to the server's repre‐
52 sentation of an index on this collection. If the collection does not
53 exist on the server, the cursor will be empty.
54
55 The cursor functions mongoc_cursor_set_limit, mongoc_cur‐
56 sor_set_batch_size, and mongoc_cursor_set_max_await_time_ms have no use
57 on the returned cursor.
