C/C++ : converting std::string to const char* I get the error : left of '.c_str' must have class/struct/union type is 'char *' C# to C++ dll - how to pass strings as In/Out parameters to unmanaged functions that expect a string (LPSTR) as a function parameter. C++ int to str...
There was a change in VS 2022 to make VS more compliant with the C++ standard and make std::mutex a constexpr. However, this causes problems if an older version of the runtime is loaded first - in which case, the chiapos wheel will often crash. ...
It is well-known on compile time so you can write constexpr function: You can write a function to achieve this: /*constexpr*/ bool is_little_endian() { std::uint16_t x=0x0001; auto p = reinterpret_cast<std::uint8_t*>(&x); return *p != 0; } Explanation: the binary represe...
Using a pointer-to-member type here seems like a bad choice. This would probably be better: //Empty struct so not passed at runtime.struct__zero_type{//Only accept a constant integer 0 argument.constexpr__zero_type(intn) __attribute__((enable_if(n ==0,"comparison only supported with...
You can make one of the following adjustments to make the destructor be called property: changeconstexprsecure_location_t toconstevalsecure_location_t remove the unused default argument from stream wrapped_stream(const source_information_t& source = {}...

I kind of confirmed it this: static constexpr auto Width = INT_MIN; fails to compile because: error C2398: Element ‘1’: conversion from ‘const int’ to ‘const uint32_t &’ requires a narrowing conversion Not sure how I feel about this. 😃 Thanks for you help!...

binary 32bit number from file, and you know it is big endian. Your code has to be generic and works properly on big endian (e.g. ARM) and little endian (e.g. x86) systems. So you have to check the byte order. It is well-known on compile time so you can writeconstexprfunction...
