mongoc_client_pool_set_apm_callbacks()¶

Synopsis¶

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 destroyed at any time after. If a context is passed, it is the application’s responsibility to ensure context remains valid for the lifetime of the pool.

Parameters¶

pool: A mongoc_client_pool_t.
callbacks: A mongoc_apm_callbacks_t.
context: Optional pointer to include with each event notification.

Returns¶

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

Thread Safety¶

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