NAME

       mongoc_topology_description_has_readable_server                                          -
       mongoc_topology_description_has_readable_server()

SYNOPSIS

          bool
          mongoc_topology_description_has_readable_server (
            const 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.
