NAME

6       mongoc_database_get_collection_names_with_opts      -      mongoc_data‐
7       base_get_collection_names_with_opts()

SYNOPSIS

10          char **
11          mongoc_database_get_collection_names_with_opts (mongoc_database_t *database,
12                                                          const bson_t *opts,
13                                                          bson_error_t *error)
14             BSON_GNUC_WARN_UNUSED_RESULT;
15
16       Fetches a NULL terminated array of NULL-byte terminated  char*  strings
17       containing the names of all of the collections in database.
18
19       This  function  is considered a retryable read operation.  Upon a tran‐
20       sient error (a network error, errors due to replica set failover, etc.)
21       the  operation  is  safely retried once.  If retryreads is false in the
22       URI (see mongoc_uri_t) the retry behavior does not apply.
23

PARAMETERS

25       • database: A mongoc_database_t.
26
27       • opts: A bson_t containing additional options.
28
29       • error: An optional location for a bson_error_t or NULL.
30
31       opts may be NULL or a BSON document with additional command options:
32
33       • sessionId:   First,   construct   a   mongoc_client_session_t    with
34         mongoc_client_start_session().  You  can  begin  a  transaction  with
35         mongoc_client_session_start_transaction(),    optionally    with    a
36         mongoc_transaction_opt_t  that  overrides  the options inherited from
37         database, and use mongoc_client_session_append() to add  the  session
38         to opts. See the example code for mongoc_client_session_t.
39
40       • serverId:  To  target  a specific server, include an int32 "serverId"
41         field. Obtain the id by calling  mongoc_client_select_server(),  then
42         mongoc_server_description_id() on its return value.
43
44       For a list of all options, see the MongoDB Manual entry on the listCol‐
45       lections command.
46

ERRORS

48       Errors are propagated via the error parameter.
49

RETURNS

51       A NULL terminated array of NULL terminated char* strings that should be
52       freed with bson_strfreev(). Upon failure, NULL is returned and error is
53       set.
54

EXAMPLES

56          {
57             bson_t opts = BSON_INITIALIZER;
58             mongoc_read_concern_t *rc;
59             bson_error_t error;
60             char **strv;
61             unsigned i;
62
63             rc = mongoc_read_concern_new ();
64             mongoc_read_concern_set_level (rc, MONGOC_READ_CONCERN_LEVEL_MAJORITY);
65             mongoc_read_concern_append (rc, &opts);
66             if ((strv = mongoc_database_get_collection_names_with_opts (
67                    database, &opts, &error))) {
68
69                for (i = 0; strv[i]; i++)
70                   printf ("%s\n", strv[i]);
71
72                bson_strfreev (strv);
73             } else {
74                fprintf (stderr, "Command failed: %s\n", error.message);
75             }
76
77             mongoc_read_concern_destroy (rc);
78             bson_destroy (&opts);
79          }
