 | |The callback function `log_access()` is called when CivetWeb is about to log a message. If the callback function returns 0, CivetWeb will use the default internal access log routines to log the access. If a non-zero value is returned, CivetWeb assumes that access logging has already been done and no further action is performed.|

 | |The callback function `init_ssl()` is called when CivetWeb initializes the SSL library. The parameter `user_data` contains a pointer to the data which was provided to `mg_start()` when the server was started. The callback function can return 0 to signal that CivetWeb should setup the SSL certificate. With a return value of 1 the callback function signals CivetWeb that the certificate has already been setup and no further processing is necessary. The value -1 should be returned when the SSL initialization fails.|
