обычно работает хорошо, но иногда дает сбой в & :: Proto :: _ DisconnectClient_default_instance _);
Это программа на С ++ для linux.
inline const ::Proto::DisconnectClient& GateCommand::disconnectclient() const {
const ::Proto::DisconnectClient* p = disconnectclient_;
// @@protoc_insertion_point(field_get:Proto.GateCommand.disconnectclient)
return p != NULL ? *p : *reinterpret_cast<const ::Proto::DisconnectClient*>(
