All #pragma are by definition compiler specific so it would depend on the compiler you are using.

However if it we MSVC++ then this pragma can be put in a header file to stop it being included more than once during compilation in much the same way that people noremally use

Expand|Select|Wrap|Line Numbers
  1. #ifndef FILE_INCLUDED
  2. #define FILE_INCLUDED
  3.  
  4. #endif
why compiler gives "lvalue requirement" errors
I have no idea perhaps you should post the code and the actual errors.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
