mongoc_topology_description_has_writable_server - mongoc_topology_description_has_writable_server()
bool mongoc_topology_description_has_writable_server ( mongoc_topology_description_t *td); Determines if the topology has a writable server available, such as a primary, mongos, or standalone. 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. Use this function in a topology-changed callback registered with mongoc_apm_set_topology_changed_cb. For historical reasons, the mongoc_topology_description_t passed to the callback is a const pointer, you must cast away const to pass the pointer to mongoc_topology_description_has_writable_server.
· td: A mongoc_topology_description_t.
True if there is a known writable server.
