mongoc_topology_description_has_readable_server() — None

Synopsis

bool
mongoc_topology_description_has_readable_server (mongoc_topology_description_t *td,
                                                 const mongoc_read_prefs_t     *prefs);

Determines if the topology has a readable server available. Servers are filtered by the given read preferences only if the driver is connected to a replica set, otherwise the read preferences are ignored. This function uses the driver's current knowledge of the state of the MongoDB server or servers it is connected to; it does no I/O and it does not block.

Parameters

td
A mongoc_topology_description_t
read_prefs
A mongoc_read_prefs_t or NULL for default read preferences.

Returns

True if there is a known server matching prefs
