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)
             BSON_GNUC_WARN_UNUSED_RESULT;

       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);
             }
          }
