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.
