SYNOPSIS

          typedef void (*mongoc_apm_topology_opening_cb_t) (
             const mongoc_apm_topology_opening_t *event);

          void
          mongoc_apm_set_topology_opening_cb (mongoc_apm_callbacks_t *callbacks,
                                              mongoc_apm_topology_opening_cb_t cb);

       mongoc_topology_description_t.

PARAMETERS

       • callbacks: A mongoc_apm_callbacks_t.

       • cb: A  function  to  call  with  a  mongoc_apm_topology_opening_t  whenever  the  driver
