mongoc_client_set_apm_callbacks()¶

Synopsis¶

bool
mongoc_client_set_apm_callbacks (mongoc_client_t *client,
                                 mongoc_apm_callbacks_t *callbacks,
                                 void *context);

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

The callbacks are copied by the client 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 client.

Parameters¶

client: A mongoc_client_t.
callbacks: Optional mongoc_apm_callbacks_t. Pass NULL to clear all callbacks.
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.
