NAME

       mongoc_topology_description_has_writable_server - mongoc_topology_description_has_writable_server()

SYNOPSIS

          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.

PARAMETERS

       • td: A mongoc_topology_description_t.

RETURNS

       True if there is a known writable server.
