es_handler_block_t

Declaration

typealias es_handler_block_t = (OpaquePointer, UnsafePointer<es_message_t>) -> Void

Discussion

The block receives two parameters:

• The client that receives the event, as an es_client_t pointer. You pass this client to any es_respond-prefixed functions that you call in the handler.

• The message to handle, as an es_message_t pointer.

You implement the handler by inspecting the message and deciding how to respond to it. For example, your handler might receive a message with event_type ES_EVENT_TYPE_AUTH_RENAME, indicating that the system wants authorization before renaming a file. Your handler would call es_respond_auth_result(_:_:_:_:) to permit or deny the renaming.
