NAME

6       mongoc_topology_description_has_writable_server  -  mongoc_topology_de‐
7       scription_has_writable_server()
8

SYNOPSIS

10          bool
11          mongoc_topology_description_has_writable_server (
12             const mongoc_topology_description_t *td);
13
14       Determines if the topology has a writable server available, such  as  a
15       primary, mongos, or standalone. This function uses the driver's current
16       knowledge of the state of the MongoDB server or servers it is connected
17       to; it does no I/O and it does not block.
18
19       Use  this  function in a topology-changed callback registered with mon‐
20       goc_apm_set_topology_changed_cb.  For  historical  reasons,  the   mon‐
21       goc_topology_description_t  passed  to the callback is a const pointer,
22       you must cast away const to pass  the  pointer  to  mongoc_topology_de‐
23       scription_has_writable_server.
24

PARAMETERS

26       • td: A mongoc_topology_description_t.
27

RETURNS

29       True if there is a known writable server.
