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

PARAMETERS

19       • client: A mongoc_client_t.
20
21       • opts: A bson_t containing additional options.
22
23       • error: An optional location for a bson_error_t or NULL.
24
25       opts may be NULL or a BSON document with additional command options:
26
27       • sessionId:  First,  construct  a  mongoc_client_session_t  with  mon‐
28         goc_client_start_session.  You  can  begin  a  transaction  with mon‐
29         goc_client_session_start_transaction, optionally with a mongoc_trans‐
30         action_opt_t  that  overrides  the options inherited from client, and
31         use mongoc_client_session_append to add the session to opts. See  the
32         example code for mongoc_client_session_t.
33
34       • serverId:  To  target  a specific server, include an int32 "serverId"
35         field. Obtain the id  by  calling  mongoc_client_select_server,  then
36         mongoc_server_description_id on its return value.
37
38       This  function  is considered a retryable read operation.  Upon a tran‐
39       sient error (a network error, errors due to replica set failover, etc.)
40       the  operation  is  safely retried once.  If retryreads is false in the
41       URI (see mongoc_uri_t) the retry behavior does not apply.
42

ERRORS

44       Errors are propagated via the error parameter.
45

RETURNS

47       A NULL terminated vector of NULL-byte terminated  strings.  The  result
48       should be freed with bson_strfreev().
49
50       NULL is returned upon failure and error is set.
51

EXAMPLES

53          {
54             bson_error_t error;
55             char **strv;
56             unsigned i;
57
58             if ((strv = mongoc_client_get_database_names_with_opts (client, NULL, &error))) {
59                for (i = 0; strv[i]; i++)
60                   printf ("%s\n", strv[i]);
61                bson_strfreev (strv);
62             } else {
63                fprintf (stderr, "Command failed: %s\n", error.message);
64             }
65          }
