SYNOPSIS

bool
mongoc_topology_description_has_readable_server (

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.
