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. 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.
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. For a list of all options, see the MongoDB Manual entry on the listDatabases command.
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); } }
