       • pool: A mongoc_client_pool_t.

       • callbacks: A mongoc_apm_callbacks_t.

       • context: Optional pointer to include with each event notification.

       Returns true on success. If any arguments are invalid, returns false and logs an error.

          bool
          mongoc_client_pool_set_apm_callbacks (mongoc_client_pool_t *pool,
                                                mongoc_apm_callbacks_t *callbacks,
                                                void *context);

       Register a set of callbacks to receive Application Performance Monitoring events.

       The  callbacks  are  copied  by  the  pool  and may be safely destroyed by the caller after this API call
       completes.  If a context is passed, it is the application's  responsibility  to  ensure  context  remains
       valid for the lifetime of the pool.

       This  function  can  only  be  called  once  on  a  pool,  and  must  be  called before the first call to
       mongoc_client_pool_pop().
