Use a std::wstring
instead of a C99 variable length array. The current standard guarantees a contiguous buffer for std::basic_string
. E.g.,
std::wstring wc( cSize, L'#' );
mbstowcs( &wc[0], c, cSize );
C++ does not support C99 variable length arrays, and so if you compiled your code as pure C++, it would not even compile.
With that change your function return type should also be std::wstring
.
Remember to set relevant locale in main
.
E.g., setlocale( LC_ALL, "" )
.
