td_log_message_callback_ptr typedef
A type of callback function that will be called when a message is added to the internal TDLib log.
\param verbosity_level Log verbosity level with which the message was added from -1 up to 1024. If 0, then TDLib will crash as soon as the callback returns. None of the TDLib methods can be called from the callback. \param message Null-terminated UTF-8-encoded string with the message added to the log.

typedef td_log_message_callback_ptr = ffi.Pointer<
ffi.NativeFunction<
ffi.Void Function(
ffi.Int32 verbosity_level, ffi.Pointer<pkg_ffi.Utf8> message)>>;
