How do I interoperate with C APIs std::mdspan (proposals) in C++?

Interoperating with C APIs using std::mdspan (proposals) in C++ can enhance performance for multi-dimensional data management. It allows C++ developers to seamlessly work with data structures defined in C, while benefiting from the modern features provided by C++20 and beyond.

#include #include // C API function that returns a pointer to a 2D array extern "C" double* get_data(); int main() { // Wrap the C pointer in a std::mdspan double* data = get_data(); std::mdspan> mdspan_data(data); // Accessing elements using std::mdspan for (size_t i = 0; i < mdspan_data.extent(0); ++i) { for (size_t j = 0; j < mdspan_data.extent(1); ++j) { std::cout << mdspan_data(i, j) << " "; } std::cout << std::endl; } return 0; }
