NAME

       mongoc_client_get_database_names_with_opts - mongoc_client_get_database_names_with_opts()

SYNOPSIS

          char **
          mongoc_client_get_database_names_with_opts (mongoc_client_t *client,
                                                      const bson_t *opts,
                                                      bson_error_t *error);

       This function queries the MongoDB server for a list of known databases.

PARAMETERS

       • client: A mongoc_client_t.

       • opts: A bson_t containing additional options.

       • error: An optional location for a bson_error_t or NULL.

       opts may be NULL or a BSON document with additional command options:

       • sessionId: First, construct a mongoc_client_session_t with mongoc_client_start_session. You can begin a
         transaction  with  mongoc_client_session_start_transaction,  optionally with a mongoc_transaction_opt_t
         that overrides the options inherited from client,  and  use  mongoc_client_session_append  to  add  the
         session to opts. See the example code for mongoc_client_session_t.

       • serverId:  To  target  a  specific  server, include an int32 "serverId" field. Obtain the id by calling
         mongoc_client_select_server, then mongoc_server_description_id on its return value.

       This function is considered a retryable read operation.  Upon a transient error (a network error,  errors
       due  to  replica set failover, etc.) the operation is safely retried once.  If retryreads is false in the
       URI (see mongoc_uri_t) the retry behavior does not apply.

ERRORS

       Errors are propagated via the error parameter.

RETURNS

       A  NULL  terminated  vector  of  NULL-byte  terminated  strings.  The  result  should   be   freed   with
       bson_strfreev().

       NULL is returned upon failure and error is set.

EXAMPLES

          {
             bson_error_t error;
             char **strv;
             unsigned i;

             if ((strv = mongoc_client_get_database_names_with_opts (client, NULL, &error))) {
                for (i = 0; strv[i]; i++)
                   printf ("%s\n", strv[i]);
                bson_strfreev (strv);
             } else {
                fprintf (stderr, "Command failed: %s\n", error.message);
             }
          }
