NAME

6       mongoc_client_get_database_names_with_opts   -  mongoc_client_get_data‐
7       base_names_with_opts()

SYNOPSIS

10          char **
11          mongoc_client_get_database_names_with_opts (mongoc_client_t *client,
12                                                      const bson_t *opts,
13                                                      bson_error_t *error)
14             BSON_GNUC_WARN_UNUSED_RESULT;
15
16       This function queries the MongoDB server for a list of known databases.
17
18       This function is considered a retryable read operation.  Upon  a  tran‐
19       sient error (a network error, errors due to replica set failover, etc.)
20       the operation is safely retried once.  If retryreads is  false  in  the
21       URI (see mongoc_uri_t) the retry behavior does not apply.
22

PARAMETERS

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

ERRORS

47       Errors are propagated via the error parameter.
48

RETURNS

50       A  NULL  terminated  vector of NULL-byte terminated strings. The result
51       should be freed with bson_strfreev().
52
53       NULL is returned upon failure and error is set.
54

EXAMPLES

56          {
57             bson_error_t error;
58             char **strv;
59             unsigned i;
60
61             if ((strv = mongoc_client_get_database_names_with_opts (client, NULL, &error))) {
62                for (i = 0; strv[i]; i++)
63                   printf ("%s\n", strv[i]);
64                bson_strfreev (strv);
65             } else {
66                fprintf (stderr, "Command failed: %s\n", error.message);
67             }
68          }
