For simple cases that's fine, but it can get messy fast when there are multiple structs and different fields require initialisation in different contexts (Linux USB for example). I have resorted to mixing C and C++ TUs to work around the lack of designated initialisers in C++. -- Ian. |

At times, when sausages or negativity are on your mind, it's like these ideas prevent ordinary thinking, reducing you. - Alf |
