On libc++ (or libstdc++ in -std=gnu++XX mode) they’re both true; on libstdc++ in -std=c++XX mode they’re both false.

Nettet10. nov. 2024 · The integral types are char, short (or short int ), int, long, and long long. These types may be qualified with signed or unsigned, and unsigned can be used as shorthand for unsigned int. Signed to unsigned Objects of signed integral types can be converted to corresponding unsigned types. Nettet2 dager siden · The C++ code has undefined behavior if api_init actually accesses through the casted pointer. It is not possible to do this kind of reinterpretation in standard C++ even if the structs share a common initial sequence. (However, it will work on current compilers in practice.) If it wasn't for the extern "C" then this would be C anyway. ej連結チューブ新規格
